[Bug 1585587] [NEW] Missing unix.ko in 4.6 initrd prevents LVM boot

Public bug reported:

Somehow recently the default kernel config for kernel 4.6 was changed
from CONFIG_UNIX=y to CONFIG_UNIX=m.

This however prevents systems with full disk encryption to start
properly, as the lvm encryption tools require unix sockets during set-up
in the initrd.

The proper fix would either be to restore CONFIG_UNIX=y or to force the
unix.ko module to always be included (and loaded) in the initrd. The
latter is likely to be the better approach, thus filing this against
initramfs-tools.

** Affects: initramfs-tools (Ubuntu)
     Importance: Undecided
         Status: New

** Affects: lvm2 (Ubuntu)
     Importance: Undecided
         Status: New
