[Bug 1688890] [NEW] initramfs-zfs should support misc /dev dirs

[Jens Elkner]

Public bug reported:

Right now 'zfs-initramfs', i.e. /usr/share/initramfs-tools/scripts/zfs
does not support any other directory than /dev for "zpool import ...".
Therefore even if a pool gets created from a different directory like
/dev, say /dev/disk/by-id or /dev/chassis/SYS on next reboot /dev will
be used and thus zpool status will show the /dev/sd* etc. on successful
import. Beside that now a user does not see the original names used in
"zpool create ..." the unstable names like "/dev/sd*" are shown, which
is explicitly NOT recommended.

The following patch introduces the "pseudo" kernel param named "zdirs" -
a comma separated list of dev dirs to scan on import - which gets used
by /usr/share/initramfs-tools/scripts/zfs to honor it.

** Affects: zfs-linux (Ubuntu)
     Importance: Undecided
         Status: New

** Package changed: grub2 (Ubuntu) => zfs-linux (Ubuntu)
