* Add bootfs.snapshot and bootfs.rollback kernel parametersgregory-lee-bartholomew2020-05-291-0/+24
| | | | | | | | | | | | Unlike other filesystems, snapshots and rollbacks of bootfs need to be done from a rescue environment. This patch makes it possible to snap- shot or rollback the bootfs simply by specifying bootfs.snapshot or bootfs.rollback on the kernel command line. The operation will be performed by dracut just before bootfs is mounted.

* Removed suggestion to use root dataset as bootfsGregor Kopka2019-01-081-6/+0
| | | | | | | | | | | | | | | | | The dracut howto proposed to boot from the root dataset of a pool. Apart from this giving problems when booting (as the code seems to expect a child dataset and creates an illegal dataset name when using the root dataset) the technical limitations of the root dataset (among others the inability to rename or destroy through the `zfs` command) resulted in the general consensus to only use it as a container for the datasets in the pool - not as a filesystem itself. Removed the idea to boot from the root dataset.

* Move dracut directory to contribBrian Behlendorf2015-07-091-0/+207
The dracut code is analogous to the initramfs code and as such it should be located in the contrib with initramfs for consistency. Signed-off-by: Brian Behlendorf <[email protected]>
