Bug#266591: initrd-tools: mkinitrd assumes /dev/mapper/* == LVM device

["Nathaniel W. Turner" <nate@houseofnate.net>]

Package: initrd-tools
Version: 0.1.73
Severity: important

I have cryptsetup installed and my /etc/crypttab contains:

swap0             /dev/hda7       /dev/urandom      swap

This creates an encrypted device /dev/mapper/swap0 (which I mount as
swap in /etc/fstab).

When installing kernel-image-2.6.8-1-k7, I get the following error:

Setting up kernel-image-2.6.8-1-k7 (2.6.8-1) ...
/usr/sbin/mkinitrd: /dev/mapper/swap0: Cannot find LVM device
Failed to create initrd image.
dpkg: error processing kernel-image-2.6.8-1-k7 (--configure):
 subprocess post-installation script returned error exit status 9

As far as I can tell, mkinitrd is assuming that anything in /dev/mapper
is an LVM device, which is not a safe assumption.

Cheers,
nate
