Bug#429144: mkinitrd creates unusable initrd

[Henning Sprang <henning_sprang@gmx.de>]

Package: initramfs-tools
Version: 0.85e
Tag: patch

mkinitramfs creates a broken initrd, when accidentally the MODULES 
parameter is wrong in /etc/initramfs-tools/initramfs.conf.

This can create major problems, and it's not so easy to find the source 
of this problem

Compared to this, it's very easy to add the attached patch, which makes 
mkinitramfs check if the MODULES setting is useable and will not lead to 
an unusable initrd.
