running e2fsk (+some options) while it fixed an error it did not help. I have started making backups and am prepared to re-install debian. Any last ideas before i do this?
before re-mounting it as read/write again, make sure you did a "e2fsck /dev/<your-harddisk-device>". looks like the filesystem got somewhat corrupted when your system crashed; e2fsck might fix it. If e2fsck ran successfully, reboot again - and see what happens. if you still have the problem that many init scripts won't run (usually "could not load file ..." or segmentation faults), your installation is seriously broken. consider re-installing.
