Title:
initramfs cryptroot hook script doesn't install cryptsetup if keyfile
but no keyscript
Status in cryptsetup package in Ubuntu:

Status in cryptsetup source package in Xenial:

Bug description:
When crypttab specifies a key-file for the container of the root file-
system but there is no keyscript= option no cryptsetup support is
installed in the initrd.img.
Currently the cryptroot initramfs hook script knows its a problem and
will report:
cryptsetup: WARNING: target LUKS_OS uses a key file, skipped
This is BAD behaviour that renders the root file-system container
inaccessible at boot time.
Regardless of a key-script being available cryptsetup support should
be installed into the initrd.img to enable the user to take manual
steps to unlock the container. The hook script has no knowledge about
pass phrases that might be set in other LUKS slots that are available
to the user.
This is the behaviour when a keyscript is specified but doesn't exist.
The attached patch modifies the behaviour to include cryptsetup in the
initrd.img and modify the warning to the user.
cryptsetup: WARNING: target LUKS_OS uses a key file, but no keyscript
is set. Please ensure there is also a typed pass-phrase set.
