Bug#450888: initramfs-tools: should depend on findutils >= 4.2.24

[Aurelien Jacobs <aurel@gnuage.org>]

Package: initramfs-tools
Version: 0.90a

mkinitramfs uses the -regextype option of find. This options was introduced
in findutils 4.2.24.
I've tried to use a recent version of initramfs-tools on an old sarge
powerpc install. Here is the result:

# update-initramfs -u
update-initramfs: Generating /boot/initrd.img-2.6.22-2-powerpc
find: invalid predicate `-regextype'
find: invalid predicate `-regextype'

This generated a non bootable system (kernel panic: init killed).

Updating findutils and re-generating the initramfs, fixed my system.

I'm not sure if such a hackish update from sarge to lenny is supported,
but simply adding a dependency on findutils >= 4.2.24 would solve this
issue.
