What I'm afraid of, is that if you have 200 users logged in your box, you will have 200 mountpoints, one mountpoint per each holy user!!! I really feel bad about it. Am I wrong?
No, you aren't wrong, but there are things to consider. Generally our machines have less than 50 people logged in at a time (usually less than 10) and that isn't too bad for the automounter to handle. If you've got some big central servers with lots of users logged in at a time, this might get a little tough. I'm not sure when the number of automounts causes a performance hit on NFS clients. What you don't want is a bunch of automounts getting triggered at the same time. The ensuing mount storm can swamp even the speediest box.
We've got a pretty centralized environment though and have never had a problem with this so far. Does anyone else have relevant experience?
