Make sure that POOL_IMPORTED is set, unset and checked where appropriate.
* If it's unset in find_rootfs(), no pool is imported so no point in looking for a rootfs. * If find_rootfs() couldn't find a rootfs, the pool is exported. Remember to unset POOL_IMPORTED after doing so. * Set POOL_IMPORTED if/when a pool have been imported in import_pool(). * Improve backup import (the one using cache file). Signed-off-by: Turbo Fredriksson <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Closes #3636
