Package: initramfs-tools
Version: 0.94.4
Severity: normal
Tags: patch
mkinitramfs fails to generate a initrd file for root filesystems on an
old mylex raid controller (kernel module DAC960).
In my case this breaks installation for lenny (5.0.3) on a FJS Primergy
server - as this bug is not only in the mentioned version but also in
0.92 which ships on the lenny install cd: The installer can boot, as the
old kernel module is still present. But the base install step fails when
it tries to generate the initrd.
The error in detail, when invoking mkinitramfs manually with -x

-------------
So the reason is that mkinitramfs fails to derive the correct block
device notation from the root device as the DAC960 driver uses a strange
format for it.
Once figured out, this is easily corrected. Please find a short patch
for /usr/share/initramfs-tools/hook-functions attached.
Thank you,
