Comment 16 for bug 1423796

I just ran into this with a cleanly installed 17.04. Figured it out myself, added "copy_exec /usr/sbin/cache_check" to /usr/share/initramfs-tools/hooks/lvm2 in order to fix it.

Can we PLEASE get this bug -- which renders systems UNBOOTABLE after attaching a cache -- fixed, especially since there are good and reasonable patches available already (#12)?
