Bug#491443: /var/lib/initramfs-tools/ not updated

[Cesare Leonardi <celeonar@ngi.it>]

Package: initramfs-tools
Version: 0.92e
Severity: minor

Today i've changed "update_initramfs" variable from "yes" to "all".
The update-initramfs scripts seems to look at the contents of the 
directory "/var/lib/initramfs-tools/" to know for what image to update 
(it contain MD5 files, one for every initramfs created in this system).
The problem is that nobody seems to care of cleaning that directory 
after a kernel removal, so it is full of obsolete files, that makes 
update-initramfs a bit noisy. On my system:

# update-initramfs -u
update-initramfs: Generating /boot/initrd.img-2.6.25-2-686

In fact i've only the first two kernel installed.
Maybe when a kernel get purged, the removal scripts should clean its 
files under /var.
