Patch to check initramfs generator availability

[Frans Pop <aragorn@tiscali.nl>]

I'm considering a patch for the base-installer postinst to check if the
default generators are actually available.
For example, even if both are defined in base-installer for an arch, it
is possible that only one is included on a netinst CD.

This patch would have the following check ($irf being yaird or
initramfs-tools):
   if chroot /target apt-cache policy $irf | \
      grep "Candidate:" | grep -v "(none)" >/dev/null 2>&1; then
           # generator is available
   fi

I have tested that this test works, but am unsure if the use of apt-cache
is the best option?

Cheers,
FJP
