Bug#503062: News?

If you manage to reproduce it (with 2.6.26 for example) please provide
the log from update-initramfs. You don't build your kernel with
make-kpkg (which, at install time, will generate the initrd itself)?
Yes, what I'm describing here is what I've just done to verify whether
the problem would recur when installing 2.6.26.7, and it's what I'm
always doing (except that usually I do the build in /usr/src/linux and
just update and reset the git branches there instead from creating a new
git repo); linux-initrd-createinstall is really just a thin wrapper
around update-initramfs which I created because I always forgot the name
of that tool ('cause the name of the tool to create the initrd's changed
over time, after all; I'm attaching it just in case you've got time to
waste to look at it):

Now let's see what's in the newly created initrd:
chris@novo:/tmp/chris$ for f in initrd.img-2.6.26.7; do cdnewdir $f;
zcat /boot/$f | cpio --extract ; find|sort > ../$f.list ; u ; done
34109 blocks
chris@novo:/tmp/chris$ map $(lambda 'perl -wne "s|/2\\.6\\.2.\\..|/| or
print"') $(lambda 'diff -u "$@"') initrd.img-2.6.26.5_fixednewc.list
initrd.img-2.6.26.7.list
# again no difference in the list of non-versioned files from good
manually fixed initrd.
chris@novo:/tmp/chris$ cat initrd.img-2.6.26.7/conf/conf.d/cryptroot
target=sda8_crypt,source=/dev/sda8,key=none,lvm=main-root
So: the file is also in the newly built /boot/initrd.img-2.6.26.7 now.
So my only explanation is that the problem has been fixed in
initramfs-tools with an upgrade I did after reporting the bug. Actually
I was somewhat more hesitant with upgrading after a few bigger breakages
in lenny, so at that point in time I may have been running a version of
the initramfs-tools that was a few weeks old -- but you should see that
from the bug report, shouldn't you? yep, the report says "Version:
0.92j". I'm now running:
chris@novo:~$ dpkgli initramfs-tools
ii initramfs-tools 0.92j tools for generating an initramfs
Ehr, wait, isn't this the same version?
Oh well, so much for the theory. So what am I gonna to do, try to build
2.6.26.6 again just for * sake and not use the -v flag to the
update-initramfs script in case it should turn out to be a heisenbug?

do you want to look at the output?

Well now I'm really out of ideas.
novo:/etc# find -name '*cryptroot*'
novo:/etc#
I don't have the time to find out where it creates the cryptroof file
from and how it could get to fail now. Let's wish us best of luck and
hold our thumbs.
