[Bug 300742] [NEW] mkinitramfs handles errors very badly due to use of /usr/share/initramfs-tools/scripts/functions

[Forest Bond]

Public bug reported:

Binary package hint: initramfs-tools

mkinitramfs uses /usr/share/initramfs-tools/scripts/functions for
handling certain tasks.  Errors that occur in those functions cause the
panic function to be called.  This launches an interactive shell that
steals /dev/console.  If this occurs when the user is running X, the
keyboard stops working.  This is rather unpleasant.

To trigger the bug, try adding a hook with a hyphen in the filename
(i.e. /etc/initramfs-tools/hooks/foo-bar-baz).

** Affects: initramfs-tools (Ubuntu)
