Josef Sipek's message ("Ugly Bug in UnionFS" from Thu, 23 Mar 2006 05:16:30
-0500) explains the kernel oops. Do you think the rmdir problem might be
related to this bug as well? I did not mess up with the mount options again.

OT:
Btw. why does

  mount -t unionfs -o dirs=/path1/dir1=ro none /path2/dir2

not work?

Cheers,
Sebastian
