I have been looking at this a bit more, seems that this problem may not be
related to initramfs-tools itself, but to debian default 2.6.30 kernel
(2.6.30-6). I installed stable initramfs-tools in sid and rebuilt initrd,
and the same problem was present with 2.6.30 kernel, the same way it was
with sid initramfs-tools.

I also tried with a 2.6.29 kernel whose initrd was built from sid in June,
and worked as expected.

I will try to look a bit more at this when I find time.

Cheers,
