So I did in fact reboot, but still no improvements: symlinks can still
not be deleted. Since I don't have console access to the machine right
now, I can't try to run a reiserfsck --clean-attributes to see if that
resolved anything.
As it stands right now, symlinks cannot be deleted for mysterious
"Operation not permitted", despite mounting the filesystems with
"noattrs".
The system was installed in 2002 with reiserfs 3.6, so no reiserfs 3.5
conversion was ever done, IIRC.
