* Default to internal 'zfs userspace' implementationBrian Behlendorf2011-05-201-10/+0
| | | | | | | | | | | | | We will never bring over the pyzfs.py helper script from Solaris to Linux. Instead the missing functionality will be directly integrated in to the zfs commands and libraries. To avoid confusion remove the warning about the missing pyzfs.py utility and simply use the default internal support. The Illumous developers are of the same mind and have proposed an initial patch to do this which has been integrated in to the 'allow' development branch. After some additional testing this code can be merged in to master as the right long term solution.
* Fix awk usageBrian Behlendorf2011-05-062-4/+5
| | | | | | | | | | | | | | | The zpool_id and zpool_layout helper scripts have been updated to use the more common /usr/bin/awk symlink. On Fedora/Redhat systems there are both /bin/awk and /usr/bin/awk symlinks to your installed version of awk. On Debian/Ubuntu systems only the /usr/bin/awk symlink exists. Additionally, add the '\<' token to the beginning of the regex pattern to prevent partial matches. This pattern only appears to work with gawk despite the mawk man page claiming to support this extended regex. Thus you will need to have gawk installed to use these optional helper scripts. A comment has been added to the script to reflect this reality.
* Allow mounting of read-only snapshotszfs-0.6.0-rc4Brian Behlendorf2011-05-051-3/+8
| | | | | | | | With the addition of the mount helper we accidentally regressed the ability to manually mount snapshots. This commit updates the mount helper to expect the possibility of a ZFS_TYPE_SNAPSHOT. All snapshot will be automatically treated as 'legacy' type mounts so they can be mounted manually.
* Fix 'zfs set volsize=N pool/dataset'Brian Behlendorf2011-05-0211-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change fixes a kernel panic which would occur when resizing a dataset which was not open. The objset_t stored in the zvol_state_t will be set to NULL when the block device is closed. To avoid this issue we pass the correct objset_t as the third arg. The code has also been updated to correctly notify the kernel when the block device capacity changes. For 2.6.28 and newer kernels the capacity change will be immediately detected. For earlier kernels the capacity change will be detected when the device is next opened. This is a known limitation of older kernels. Online ext3 resize test case passes on 2.6.28+ kernels: $ dd if=/dev/zero of=/tmp/zvol bs=1M count=1 seek=1023 $ zpool create tank /tmp/zvol $ zfs create -V 500M tank/zd0 $ mkfs.ext3 /dev/zd0 $ mkdir /mnt/zd0 $ mount /dev/zd0 /mnt/zd0 $ df -h /mnt/zd0 $ zfs set volsize=800M tank/zd0 $ resize2fs /dev/zd0 $ df -h /mnt/zd0 Original-patch-by: Fajar A.

* Implemented NFS export_operations.Gunnar Beutner2011-04-2911-0/+11
| | | | | Implemented the required NFS operations for exporting ZFS datasets using the in-kernel NFS daemon.
* Use gethostid in the Linux convention.Darik Horn2011-04-251-1/+3
| | | | | | | | | | Disable the gethostid() override for Solaris behavior because Linux systems implement the POSIX standard in a way that allows a negative result. Mask the gethostid() result to the lower four bytes, like coreutils does in /usr/bin/hostid, to prevent junk bits or sign-extension on systems that have an eight byte long type. This can cause a spurious hostid mismatch that prevents zpool import on 64-bit systems.
* Set -Wno-unused-but-set-variable globallyBrian Behlendorf2011-04-198-25/+33
| | | | | | | | | | | | | As of gcc-4.6 the option -Wunused-but-set-variable is enabled by default. While this is a useful warning there are numerous places in the ZFS code when a variable is set and then only checked in an ASSERT(). To avoid having to update every instance of this in the code we now set -Wno-unused-but-set-variable to suppress the warning. Additionally, when building with --enable-debug and -Werror set these warning also become fatal. We can reevaluate the suppression of these error at a later time if it becomes an issue. For now we are basically just reverting to the previous gcc behavior.
* Fix gcc compiler warning, parse_option()Brian Behlendorf2011-04-191-0/+1
| | | | | | | | | | | | | | | When compiling ZFS in user space gcc-4.6.0 correctly identifies the variable 'value' as being set but never used. This generates a warning and a build failure when using --enable-debug. Once again this is correct but I'm reluctant to remove 'value' because we are breaking the string in to name/value pairs. While it is not used now there's a good chance it will be soon and I'd rather not have to reinvent this. To suppress the warning with just as a VERIFY(). This was observed under Fedora 15. cmd/mount_zfs/mount_zfs.c: In function ‘parse_option’: cmd/mount_zfs/mount_zfs.c:112:21: error: variable ‘value’ set but not used [-Werror=unused-but-set-variable]

* Call udevadm trigger more safelyNed Bass2011-04-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Some udev hooks are not designed to be idempotent, so calling udevadm trigger outside of the distribution's initialization scripts can have unexpected (and potentially dangerous) side effects. For example, the system time may change or devices may appear multiple times. See Ubuntu launchpad bug 320200 and this mailing list post for more details: https://lists.ubuntu.com/archives/ubuntu-devel/2009-January/027260.html To avoid these problems we call udevadm trigger with --action=change --subsystem-match=block. The first argument tells udev just to refresh devices, and make sure everything's as it should be. The second argument limits the scope to block devices, so devices belonging to other subsystems cannot be affected. This doesn't fix the problem on older udev implementations that don't provide udevadm but instead have udevtrigger as a standalone program. In this case the above options aren't available so there's no way to call call udevtrigger safely. But we can live with that since this issue only exists in optional test and helper scripts, and most zfs-on-linux users are running newer systems anyways.
* Fixes to enable zvol symlink creationFajar A. Nugraha2011-03-241-2/+5
| | | | | | | | | | | | This commit fixes issue on https://github.com/behlendorf/zfs/issues/#issue/172 Changes: - update BLKZNAME to use _IOR instead of _IO. Kernel 2.6.32 allows read parameters (copy_to_user) with _IO, while newer kernels (tested Archlinux's 2.6.37 kernel) enforces _IOR (which is correct) - fix return code and message on error Signed-off-by: Brian Behlendorf <[email protected]>
* Linux 2.6.28 compat, insert_inode_locked()Brian Behlendorf2011-03-2211-0/+11
| | | | | | | Added insert_inode_locked() helper function, prior to this most callers used insert_inode_hash(). The older method doesn't check for collisions in the inode_hashtable but it still acceptible for use. Fallback to using insert_inode_hash() when insert_inode_locked() is unavailable.

| * Add init scriptsBrian Behlendorf2011-03-1711-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To support automatically mounting your zfs on filesystem on boot a basic init script is needed. Unfortunately, every distribution has their own idea of the _right_ way to do things. Rather than write one very complicated portable init script, which would be invariably replaced by the distributions own anyway. I have instead added support to provide multiple distribution specific init scripts. The correct init script for your distribution will be selected by ZFS_AC_DEFAULT_PACKAGE which will set DEFAULT_INIT_SCRIPT. During 'make install' the correct script for your system will be installed from zfs/etc/init.d/zfs.DEFAULT_INIT_SCRIPT to the usual /etc/init.d/zfs location. Currently, there is zfs.fedora and a more generic zfs.lsb init script. Hopefully, the distribution maintainers who know best how they want their init scripts to function will feedback their approved versions to be included in the project. This change does not consider upstart jobs but I'm not at all opposed to add that sort of thing.
| * Strip 'zfsutil,remount' from /etc/mtabBrian Behlendorf2011-03-151-15/+28
| | | | | | | | | | | | | | | | When updating /etc/mtab we should be careful and strip certain options. In particular, we need to strip 'zfsutil' because if we don't the mount utility will helpfull provide it to the mount helper when we issue mount(8) again. This subverts the check that the caller is zfs(8) and not mount(8).
| * Always allow '-o remount,ro'Brian Behlendorf2011-03-151-3/+10
| | | | | | | | | | | | | | | | | | | | | | Allow the mount(8) utility to always operate on all datasets when remounting them read-only. This critical for rc.sysinit/umountroot which remounts the root filesystem read-only during shutdown to ensure everything is correctly flushed to disk. Fix minor typo, the check to set zfsutil should use the bitwise '&'. I must have accidentally hit the adjacent '*' and obviously neither the compiler or my code review caught this. Fix it now.
* | Fix 'LDFLAGS=-Wl,--as-needed' build errorBrian Behlendorf2011-03-182-3/+0
| | | | | | | | | | | | | | | | | | | | Compiling with 'LDFLAGS=-Wl,--as-needed' exposed the fact that there were some library linking problems introduced by mount_zfs. In particular, the libzfs library does use nvpair symbols, and mount_zfs contains no dependencies on libzpool. Closes #161 Closes #162
* | Fix getcwd() warningBrian Behlendorf2011-03-181-1/+3
|/ | | | | | | | | | | | | New versions glibc declare getcwd() with the warn_unused_result attribute. This results in a warning because the updated mount helper was not checking this return value. This issue was fixed by checking the return type and in the case of an error simply returning the passed dataset. One possible, but unlikely, error would be having your cwd directory unlinked while the mount command was running. cmd/mount_zfs/mount_zfs.c: In function ‘parse_dataset’: cmd/mount_zfs/mount_zfs.c:223:2: error: ignoring return value of ‘getcwd’, declared with attribute warn_unused_result
* Check for trailing '/' in mount.zfsBrian Behlendorf2011-03-101-2/+6
| | | | | | | | | | | | | | | | When run with a root '/' cwd the mount.zfs helper would strip not only the '/' but also the next character from the dataset name. For example, '/tank' was changed to 'ank' instead of just 'tank'. Originally, this was done for the '/tmp' cwd case where we needed to strip the '/' following the cwd. For example '/tmp/tank' needed to remove the '/tmp' cwd plus 1 character for the '/'. This change fixes the problem by checking the cwd and if it ends in a '/' it does not strip and extra character. Otherwise it will strip the next character. I believe this should only ever be true for the root directory. Closes #148
* Fix mount helperBrian Behlendorf2011-03-096-427/+1211
| | | | | | | | | | | | | | | | | Several issues related to strange mount/umount behavior were reported and this commit should address most of them. The original idea was to put in place a zfs mount helper (mount.zfs). This helper is used to enforce 'legacy' mount behavior, and perform any extra mount argument processing (selinux, zfsutil, etc). This helper wasn't ready for the 0.6.0-rc1 release but with this change it's functional but needs to extensively tested. This change addresses the following open issues. Closes #101 Closes #107 Closes #113 Closes #115 Closes #119
* Add xvattr supportBrian Behlendorf2011-03-021-0/+1
| | | | | | | | | | | | | | | With the removal of the minimal xvattr support from the spl this support needs to be replaced in the zfs package. This is fairly easily accomplished by directly adding portions of the sys/vnode.h header from OpenSolaris. These xvattr additions have been placed in the sys/xvattr.h header file and included as needed where simply a sys/vnode.h was included before. In additon to the xvattr types and helper macros two functions were also included. The xva_init() and xva_getxoptattr() functions were included as static inline functions in xvattr.h. They are simple enough and it was simpler to place them here rather than in their own .c file.
* Use udev to create /dev/zvol/[dataset_name] linksFajar A. Nugraha2011-02-255-2/+736
| | | | | | | | | | | | | | | | | This commit allows zvols with names longer than 32 characters, which fixes issue on https://github.com/behlendorf/zfs/issues/#issue/102. Changes include: - use /dev/zd* device names for zvol, where * is the device minor (include/sys/fs/zfs.h, module/zfs/zvol.c). - add BLKZNAME ioctl to get dataset name from userland (include/sys/fs/zfs.h, module/zfs/zvol.c, cmd/zvol_id). - add udev rule to create /dev/zvol/[dataset_name] and the legacy /dev/[dataset_name] symlink. For partitions on zvol, it will create /dev/zvol/[dataset_name]-part* (etc/udev/rules.d/60-zvol.rules, cmd/zvol_id). Signed-off-by: Brian Behlendorf <[email protected]>
* Fix uninitialized variableBrian Behlendorf2011-02-231-1/+1
| | | | | | It was possible for rc to be unitialized in the parse_options() function which triggered a compiler warning. Ensure rc is always initialized.
* Linux 2.6.38 compat, blkdev_get_by_path()Brian Behlendorf2011-02-239-0/+9
| | | | | | | | | | | The open_bdev_exclusive() function has been replaced (again) by the more generic blkdev_get_by_path() function. Additionally, the counterpart function close_bdev_exclusive() has been replaced by blkdev_put(). Because these functions are more generic versions of the functions they replaced the compatibility macro must add the FMODE_EXCL mask to ensure they are exclusive. Closes #114
* Linux 2.6.36 compat, sops->evict_inode()Brian Behlendorf2011-02-119-0/+9
| | | | | | The new prefered inteface for evicting an inode from the inode cache is the ->evict_inode() callback. It replaces both the ->delete_inode() and ->clear_inode() callbacks which were previously used for this.
* Linux 2.6.35 compat, fops->fsync()Brian Behlendorf2011-02-119-0/+9
| | | | | | | | | The fsync() callback in the file_operations structure used to take 3 arguments. The callback now only takes 2 arguments because the dentry argument was determined to be unused by all consumers. To handle this a compatibility prototype was added to ensure the right prototype is used. Our implementation never used the dentry argument either so it's just a matter of using the right prototype.
* Linux 2.6.35 compat, const struct xattr_handlerBrian Behlendorf2011-02-109-0/+9
| | | | | | | The const keyword was added to the 'struct xattr_handler' in the generic Linux super_block structure. To handle this we define an appropriate xattr_handler_t typedef which can be used. This was the preferred solution because it keeps the code clean and readable.
* MS_DIRSYNC and MS_REC compatBrian Behlendorf2011-02-101-0/+2
| | | | | | | | | | | | | It turns out that older versions of the glibc headers do not properly define MS_DIRSYNC despite it being explicitly mentioned in the man pages. They instead call it S_WRITE, so for system where this is not correct defined map MS_DIRSYNC to S_WRITE. At the time of this commit both Ubuntu Lucid, and Debian Squeeze both use the out of date glibc headers. As for MS_REC this field is also not available in the older headers. Since there is no obvious mapping in this case we simply disable the recursive mount option which used it.
* Add missing -ldl linker optionBrian Behlendorf2011-02-108-8/+8
| | | | | | The inclusion on dlsym(), dlopen(), and dlclose() symbols require us to link against the dl library. Be careful to add the flag to both the libzfs library and the commands which depend on the library.
* Remove HAVE_ZPL from commands and librariesBrian Behlendorf2011-02-043-48/+0
| | | | | Thanks to the previous few commits we can now build all of the user space commands and libraries with support for the zpl.
* Documentation updatesBrian Behlendorf2011-02-042-10/+10
| | | | | Minor Linux specific documentation updates to the comments and man pages.
* Minimal libshare infrastructureBrian Behlendorf2011-02-049-9/+0
| | | | | | | | | | | | | | | | | | ZFS even under Solaris does not strictly require libshare to be available. The current implementation attempts to dlopen() the library to access the needed symbols. If this fails libshare support is simply disabled. This means that on Linux we only need the most minimal libshare implementation. In fact just enough to prevent the build from failing. Longer term we can decide if we want to implement a libshare library like Solaris. At best this would be an abstraction layer between ZFS and NFS/SMB. Alternately, we can drop libshare entirely and directly integrate ZFS with Linux's NFS/SMB. Finally the bare bones user-libshare.m4 test was dropped. If we do decide to implement libshare at some point it will surely be as part of this package so the check is not needed.
* Add 'zfs mount' supportBrian Behlendorf2011-02-041-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | By design the zfs utility is supposed to handle mounting and unmounting a zfs filesystem. We could allow zfs to do this directly. There are system calls available to mount/umount a filesystem. And there are library calls available to manipulate /etc/mtab. But there are a couple very good reasons not to take this appraoch... for now. Instead of directly calling the system and library calls to (u)mount the filesystem we fork and exec a (u)mount process. The principle reason for this is to delegate the responsibility for locking and updating /etc/mtab to (u)mount(8). This ensures maximum portability and ensures the right locking scheme for your version of (u)mount will be used. If we didn't do this we would have to resort to an autoconf test to determine what locking mechanism is used. The downside to using mount(8) instead of mount(2) is that we lose the exact errno which was returned by the kernel. The return code from mount(8) provides some insight in to what went wrong but it not quite as good. For the moment this is translated as a best guess in to a errno for the higher layers of zfs. In the long term a shared library called libmount is under development which provides a common API to address the locking and errno issues. Once the standard mount utility has been updated to use this library we can then leverage it. Until then this is the only safe solution. http://www.kernel.org/pub/linux/utils/util-linux/libmount-docs/index.html
* Disable umount.zfs helperBrian Behlendorf2011-01-281-37/+103
| | | | | | | | | | | | | | | | | For the moment, the only advantage in registering a umount helper would be to automatically unshare a zfs filesystem. Since under Linux this would be unexpected (but nice) behavior there is no harm in disabling it. This is desirable because the 'zfs unmount' path invokes the system umount. This is done to ensure correct mtab locking but has the side effect that the umount.zfs helper would be called if it exists. By default this helper calls back in to zfs to do the unmount on Solaris which we don't want under Linux. Once libmount is available and we have a safe way to correctly lock and update the /etc/mtab file we can reconsider the need for a umount helper. Using libmount is the prefered solution.
* Enable mount.zfs helperBrian Behlendorf2011-01-281-32/+188
| | | | | | | | | | | | | | | | | | While not strictly required to mount a zfs filesystem using a mount helper has certain advantages. First, we need it if we want to honor the mount behavior as found on Solaris. As part of the mount we need to validate that the dataset has the legacy mount property set if we are using 'mount' instead of 'zfs mount'. Secondly, by using a mount helper we can automatically load the zpl kernel module. This way you can just issue a 'mount' or 'zfs mount' and it will just work. Finally, it gives us common hook in user space to add any zfs specific mount options we might want. At the moment we don't have any but now the infrastructure is at least in place.
* Autoconf selinux supportBrian Behlendorf2011-01-289-0/+18
| | | | | | | | | | | | | | | | | If libselinux is detected on your system at configure time link against it. This allows us to use a library call to detect if selinux is enabled and if it is to pass the mount option: "context=\"system_u:object_r:file_t:s0" For now this is required because none of the existing selinux policies are aware of the zfs filesystem type. Because of this they do not properly enable xattr based labeling even though zfs supports all of the required hooks. Until distro's add zfs as a known xattr friendly fs type we must use mntpoint labeling. Alternately, end users could modify their existing selinux policy with a little guidance.
* Fix minor compiler warningsBrian Behlendorf2011-01-062-7/+7
| | | | | | | These compiler warnings were introduced when code which was previously #ifdef'ed out by HAVE_ZPL was re-added for use by the posix layer. All of the following changes should be obviously correct and will cause no semantic changes.
* Fix block device-related issues in zdb.Ricardo M. Correia2010-12-141-9/+1
| | | | | | | | | | | Specifically, this fixes the two following errors in zdb when a pool is composed of block devices: 1) 'Value too large for defined data type' when running 'zdb <dataset>'. 2) 'character device required' when running 'zdb -l <block-device>'.

* Make rollbacks fail gracefullyNed Bass2010-11-081-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Support for rolling back datasets require a functional ZPL, which we currently do not have. The zfs command does not check for ZPL support before attempting a rollback, and in preparation for rolling back a zvol it removes the minor node of the device. To prevent the zvol device node from disappearing after a failed rollback operation, this change wraps the zfs_do_rollback() function in an #ifdef HAVE_ZPL and returns ENOSYS in the absence of a ZPL. This is consistent with the behavior of other ZPL dependent commands such as mount. The orginal error message observed with this bug was rather confusing: internal error: Unknown error 524 Aborted This was because zfs_ioc_rollback() returns ENOTSUP if we don't HAVE_ZPL, but Linux actually has no such error code. It should instead return EOPNOTSUPP, as that is how ENOTSUP is defined in user space. With that we would have gotten the somewhat more helpful message cannot rollback 'tank/fish': unsupported version This is rather a moot point with the above changes since we will no longer make that ioctl call without a ZPL. But, this change updates the error code just in case. Signed-off-by: Brian Behlendorf <[email protected]>
* Fix intermittent 'zpool add' failuresNed Bass2010-10-221-15/+27
| | | | | | | | | | | | | | | Creating whole-disk vdevs can intermittently fail if a udev-managed symlink to the disk partition is already in place. To avoid this, we now remove any such symlink before partitioning the disk. This makes zpool_label_disk_wait() truly wait for the new link to show up instead of returning if it finds an old link still in place. Otherwise there is a window between when udev deletes and recreates the link during which access attempts will fail with ENOENT. Also, clean up a comment about waiting for udev to create symlinks. It no longer needs to describe the special cases for the link names, since that is now handled in a separate helper function. Signed-off-by: Brian Behlendorf <[email protected]>
* Remove solaris-specific code from make_leaf_vdev()Ned Bass2010-10-221-37/+0
| | | | | | | Portability between Solaris and Linux isn't really an issue for us anymore, and removing sections like this one helps simplify the code. Signed-off-by: Brian Behlendorf <[email protected]>
* Add helper functions for manipulating device namesNed Bass2010-10-221-23/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This change adds two helper functions for working with vdev names and paths. zfs_resolve_shortname() resolves a shorthand vdev name to an absolute path of a file in /dev, /dev/disk/by-id, /dev/disk/by-label, /dev/disk/by-path, /dev/disk/by-uuid, /dev/disk/zpool. This was previously done only in the function is_shorthand_path(), but we need a general helper function to implement shorthand names for additional zpool subcommands like remove. is_shorthand_path() is accordingly updated to call the helper function. There is a minor change in the way zfs_resolve_shortname() tests if a file exists. is_shorthand_path() effectively used open() and stat64() to test for file existence, since its scope includes testing if a device is a whole disk and collecting file status information. zfs_resolve_shortname(), on the other hand, only uses access() to test for existence and leaves it to the caller to perform any additional file operations. This seemed like the most general and lightweight approach, and still preserves the semantics of is_shorthand_path(). zfs_append_partition() appends a partition suffix to a device path. This should be used to generate the name of a whole disk as it is stored in the vdev label. The user-visible names of whole disks do not contain the partition information, while the name in the vdev label does. The code was lifted from the function make_disks(), which now just calls the helper function. Again, having a helper function to do this supports general handling of shorthand names in the user interface. Signed-off-by: Brian Behlendorf <[email protected]>
* Add FAILFAST supportBrian Behlendorf2010-10-129-0/+9
| | | | | | | | | | | | | | | | | | | | ZFS works best when it is notified as soon as possible when a device failure occurs. This allows it to immediately start any recovery actions which may be needed. In theory Linux supports a flag which can be set on bio's called FAILFAST which provides this quick notification by disabling the retry logic in the lower scsi layers. That's the theory at least. In practice is turns out that while the flag exists you oddly have to set it with the BIO_RW_AHEAD flag. And even when it's set it you may get retries in the low level drivers decides that's the right behavior, or if you don't get the right error codes reported to the scsi midlayer. Unfortunately, without additional kernels patchs there's not much which can be done to improve this. Basically, this just means that it may take 2-3 minutes before a ZFS is notified properly that a device has failed. This can be improved and I suspect I'll be submitting patches upstream to handle this.
* Fix 'zpool events' formatting for awkBrian Behlendorf2010-10-121-4/+9
| | | | | | | | | | To make the 'zpool events' output simple to parse with awk the extra newline after embedded nvlists has been dropped. This allows the entire event to be parsed as a single whitespace seperated record. The -H option has been added to operate in scripted mode. For the 'zpool events' command this means don't print the header. The usage of -H is consistent with scripted mode for other zpool commands.

* Add [-m map] option to zpool_layoutBrian Behlendorf2010-09-171-17/+50
| | | | | | | | | | | | | | | | | By default the zpool_layout command would always use the slot number assigned by Linux when generating the zdev.conf file. This is a reasonable default there are cases when it makes sense to remap the slot id assigned by Linux using your own custom mapping. This commit adds support to zpool_layout to provide a custom slot mapping file. The file contains in the first column the Linux slot it and in the second column the custom slot mapping. By passing this map file with '-m map' to zpool_config the mapping will be applied when generating zdev.conf. Additionally, two sample mapping have been added which reflect different ways to map the slots in the dragon drawers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One of the neat tricks an autoconf style project is capable of is allow configurion/building in a directory other than the source directory. The major advantage to this is that you can build the project various different ways while making changes in a single source tree. For example, this project is designed to work on various different Linux distributions each of which work slightly differently. This means that changes need to verified on each of those supported distributions perferably before the change is committed to the public git repo. Using nfs and custom build directories makes this much easier. I now have a single source tree in nfs mounted on several different systems each running a supported distribution. When I make a change to the source base I suspect may break things I can concurrently build from the same source on all the systems each in their own subdirectory. wget -c http://github.com/downloads/behlendorf/zfs/zfs-x.y.z.tar.gz tar -xzf zfs-x.y.z.tar.gz cd zfs-x-y-z ------------------------- run concurrently ---------------------- <ubuntu system> <fedora system> <debian system> <rhel6 system> mkdir ubuntu mkdir fedora mkdir debian mkdir rhel6 cd ubuntu cd fedora cd debian cd rhel6 ../configure ../configure ../configure ../configure make make make make make check make check make check make check This change also moves many of the include headers from individual incude/sys directories under the modules directory in to a single top level include directory. This has the advantage of making the build rules cleaner and logically it makes a bit more sense.
