Package: linux-2.6
Version: 2.6.18-7, 2.6.18.dfsg.1-9
Severity: important
Attempting to install (ignore the fact that the .deb is from
www.backports.org: the problem is clearly present in the latest
versions in testing and unstable):

Hmm. The package shipped with a symbolic link
/lib/modules/2.6.18-3-k7/source
However, I can not read the target: No such file or directory
Therefore, I am deleting /lib/modules/2.6.18-3-k7/source
Running depmod.

Huh? I need symlinks properly updated, but they are not:
# cat /etc/kernel-img.conf
do_symlinks = yes
link_in_boot = yes
relative_links = yes
do_boot_enable = no
warn_initrd = no
# ls -l /boot

Here's where the problem lies: the postinst, in sub move_p().
The Perl script does hops and skips and figures out intended and
existing targets for the symlinks ($target and $vmlinuz_target,
accordingly), and if they compare equal, outputs the message
above, doing nothing else. Debugging reveals that they do
compare equal because they are both undefined/empty.
Here's how $target gets empty:
my $target = `readlink -q "${realimageloc}${kimage-$version}"`;
At the very least, interpolation of $kimage and $version is
broken. Also, since the intended pathname is a real file and
not a symlink, readlink(1) returns an empty string.
That alone wouldn't be enough, here's how $vmlinuz_target gets
the same:
my $vmlinuz_target = readlink "$kimage";
...
$vmlinuz_target = `readlink -q $vmlinuz_target`;
The $kimage link target is resolved as a symlink once again,
which fails, as it's a real file too. The whole need for doing
that second resolution, as well as mixing readlink() and
`readlink` in the same code is not clear.
I had to fix the links by hand to move on, but the problem has
to be addressed properly.
