Ok - done - I cleaned the /var before and moved to a small 50MB 

dd if=/dev/zero of=/dev/hda11
mke3fs -j /dev/hda11
mount /dev/hda11 /mnt2
( cd /var ; tar --exclude-from /root/var-exclude -cvf - * ) | (cd /mnt2 ; tar -xvf - )
umount /mnt2

Rebooted with the "new" /var - Let the machine crash, rebooted
with init=/bin/sh - dd'ed the hda11 to a file.

I now tried to fsck the file which gives me the inconsistancy:

paradigm:/tmp# ls -la

Its ~3MB.

     Why is it called "common sense" when nobody seems to have any?
