Bug#358354: 0.56 incompatible with busybox 1.01-4?

[Martijn Pieters <mj@zopatista.com>]

Package: initramfs-tools
Version: 0.56
Severity: grave

After upgrading from initramfs-tools 0.55b to 0.56 my 2.6.15-1-686-smp system
would no longer boot, and drop me into a busybox shell. Among the boot messages
busybox had printed a help message for mknod (at a glance identical to the
output of 'busybox mknod' on a working system) suggesting that initramfs-tools
had tried to use mknod in a way not supported by busybox 1.01-4.

After a boot into 2.6.14-2-686-smp (my backup boot option), a downgrade to
0.55b and regenerating my /boot/initrd.img-2.6.16-1-smp file the system booted
just fine again.
