Well, I HOPE that doesn't apply to mount -o rdonly mounts since if it
would, nullfs were REALLY broken.

The same message is in the man page of mount_union, which would be
the other, somewhat more flexible option to reach the goal I'm after,
but since nullfs is doing something much easier, I hoped it would
work.

It might even be possible to use NFS to do the job but NFS is a PITA
and in all cases much slower than nullfs (which doesn't do all too
much) or unionfs...

Can other people comment on this issue (system seems to run stable
with about 2000 mountpoints, BTW)?


Best regards,
 Gabriel
