But I think it's odd that I did the following successfully: 1. Mounted 3 ISO images from the /Source partition to /Jukebox 2. Added entries for each of the /Jukebox/... directories into 'exports' 3. Reloaded NFS 4. Successfully NFS mounted and used the files from the server How is that possible if one cannot cross filesystem boundaries on the server side? The source partition is different than the destination partition. > NIS Automounter Maps make this trivial for the clients.

The single common denominator for them is NFS. > I change my NIS Automounter Maps on-the-fly and it seems to get updated on my > Linux and Solaris NIS/NFS clients without issue. Well, you're lucky - Linux and Solaris support autofs and have consistent mechanisms for configuring them. Some of our *NIX's either don't have anything like autofs/NIS or have completely different ways of configuring them. > No, again, because NFS won't cross filesystems. I'm still confused then how I was able to perform the experiment quoted earlier. From all appearances, I *did* cross filesystems (which as I said confuses me greatly) > Unless you have remote clients dynamically run "mkisofs," possibly with rsh/ssh > commands. You're assuming again that all the client machines HAVE something even remotely like "mkisofs". A lot of them do not. > In fact, you might be looking at this wrong.

SQA is explicit about having the files they test be directly FROM the ISO image. Burning many CDs every day and shuffling them around is a nightmare, which is why we're trying to do this. > Also, I assume you've never messed with Automounter or NIS Automounter Maps, as > it makes the NFS world so much easier.
