Initramfs scripts for ZoL. * Supports booting of a ZFS snapshot. Do this by cloning the snapshot into a dataset. If this, the resulting dataset, already exists, destroy it. Then mount it on root. * If snapshot does not exist, use base dataset (the part before '@') as boot filesystem instead. * If no snapshot is specified on the 'root=' kernel command line, but there is an '@', then get a list of snapshots below that filesystem and ask the user which to use. * Clone with 'mountpoint=none' and 'canmount=noauto' - we mount manually and explicitly. * For sub-filesystems, that doesn't have a mountpoint property set, we use the 'org.zol:mountpoint' to keep track of it's mountpoint. * Allow rollback of snapshots instead of clone it and boot from the clone. * Allow mounting a root- and subfs with mountpoint=legacy set * Allow mounting a filesystem which is using nativ encryption. * Support all currently used kernel command line arguments All the different distributions have their own standard on what to specify on the kernel command line to boot of a ZFS filesystem. * Extra options: * zfsdebug=(on,yes,1) Show extra debugging information * zfsforce=(on,yes,1) Force import the pool * rollback=(on,yes,1) Rollback (instead of clone) the snapshot * Only try to import pool if it haven't already been imported * This will negate the need to force import a pool that have not been exported cleanly. * Support exclusion of pools to import by setting ZFS_POOL_EXCEPTIONS in /etc/default/zfs. * Support additional configuration variable ZFS_INITRD_ADDITIONAL_DATASETS to mount additional filesystems not located under your root dataset. * Include /etc/modprobe.d/{zfs,spl}.conf in the initrd if it/they exist. * Include the udev rule to use by-vdev for pool imports. * Include the /etc/default/zfs file to the initrd. * Only try /dev/disk/by-* in the initrd if USE_DISK_BY_ID is set. * Use /dev/disk/by-vdev before anything. * Add /dev as a last ditch attempt. * Fallback to using the cache file if that exist if nothing else worked. * Use /sbin/modprobe instead of built-in (BusyBox) modprobe. This gets rid of the message "modprobe: can't load module zcommon". Thanx to pcoultha for finding this.
