Works here:

=== Cut ===
[root@nomad tmp]# uname -a
Linux nomad.cyberbills.com 2.4.5ac4 #1 SMP Wed May 30 11:55:15 PDT 2001 i686
unknown
[root@nomad tmp]# touch 2/dummy
[root@nomad tmp]# ln -s 2/dummy very_dummy
[root@nomad tmp]# ls -l very_dummy
lrwxrwxrwx 1 root root 7 May 30 14:37 very_dummy -> 2/dummy
=== Cut ===

EXT2, loaded as module.

There are other problems (may be caused by R.Gooch's latest patch,
devfs-177) - no module autoloading complaining about "/dev//floppy/0" etc.
(there are 2 slashes after /dev, it's not a mistake). Recompiling ac5
without that patch, may be it'll help.
