What a coincidence, there is a symbolic link involved here. I have a workstation, and a gateway/fileserver machine. I export /usr on the fileserver (slave) and use amd to mount individual directories under /usr in /mnt/slave/ on the workstation. Scattered throughout the workstation are symbolic links to /mnt/slave/foo, which kick amd in gear, and make those directories available where I want them. I realize that this is not an ideal situation, but it's also very common, so if someone is going to find a bug this way, it might as well be me. :) Doug -- "The most difficult thing in the world is to know how to do a thing and to watch someone else do it wrong without comment." -- Theodore H.
