Hmmm, I have also a relict of older ReiserFS (from 2.4.4 or so) on
my HD (I´m so happy that I didn´t used it on a critical box and perhaps
never will do so ...):

/var/lug# whoami
root
/var/lug# unlink postgres.log.7.gz
unlink: unlinking `postgres.log.7.gz': Permission denied
/var/lug# rm -f postgres.log.7.gz
rm: cannot remove `postgres.log.7.gz': Permission denied

(You see the dir is /var/lug which was formerly /var/log.  I renamed the
 dir to avoid problems with each logrot run.)

What if even root has no permission to unlink or remove?

Kind regards

        Andreas.
