Bug Description
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.
