Bug#503062: initramfs-tools: /conf/conf.d/cryptroot file is missing in initrd
Package: initramfs-tools
Version: 0.92j
Severity: critical
Justification: breaks the whole system
I did install testing on my new ThinkPad last April, and choose to put
the root partition under encryption on lvm, using the offered Debian
installer functionality.
This has worked fine and I soon switched to self-built kernels, and
using update-initramfs to create the corresponding initrd's. IIRC I've
successfully installed at least two or three versions of initrd's
during this time.
(On Jun 11 I wrote a wrapper script around update-initramfs to aid me
remember which options to use.)
Somehow initrd.img-2.6.26.3 from August or September was broken and
didn't boot. It would not ask for the root partition password anymore
but just hang upon boot. On September 11 and 12 I went through the
trouble debugging the issue, and found out that the initrd was now
missing the conf/conf.d/cryptroot file. I re-added that file back to
the new initrd and the system would ask for the passphrase and boot
again. Here's the diff:

I didn't find out why this happened, but hoped that maybe somehow the
problem would fix itself (maybe by update-initramfs looking at the old
initrd, which is obviously not the case, or whatever). Now I installed
a newer kernel recently and the problem happened again.
What should I do, hack up a script that automatically fixes the
generated initrd, or where lies the problem?
