Bug#813220: initramfs-tools-core: Needs to depend on busybox

[Hilko Bengen <bengen@debian.org>]

Package: initramfs-tools-core
Version: 0.1222
Severity: grave

Dear Maintainer,

the busybox hook (/usr/share/initramfs-tools/hooks/busybox) requires
that busybox is installed.

Without busybox, it is currently not possible to generate an initrd
which breaks installation of kernel packages in the buildd chroots[1].

Cheers,
-Hilko
