Can you provide the full strace output,
Last time I filtered by symlink, and now it doesn't happen anymore.
Oh, wait - after umount and apt-get --reinstall I get the message
again.
The symlinks are in the root directory, to files in the /boot directory.
So long as your /boot directory is not mounted, both symlinks are
broken. However, as soon the package is unpacked, the /vmlinuz link
works again.
The postinst script tries to repair the /vmlinuz and /initrd.img
symlinks if they don't exist. But it does so before calling the hook
scripts that will build the initramfs, and its test for existence
actually tests what the symlink *points to*. So it decides that
the /initrd.img symlink does not exist, and needs to be recreated.
I can easily reproduce this:
