gregory-lee-bartholomew	9052e3d70b	Add bootfs.snapshot and bootfs.rollback kernel parameters ... 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.

Gregor Kopka	8bd2a2866c	Removed suggestion to use root dataset as bootfs ... 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.

Brian Behlendorf	cc49250563	Move dracut directory to contrib ... 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 <behlendorf1@llnl.gov>	2015-07-09 13:59:37 -07:00
