Yeah. NFS is really a lousy filesystem. It's just barely good
enough to use on small projects, but for serious work it just falls
apart.
At least for read/write data. It seems to work fine for mounts that
are shared read-only. Slashdot's webheads all mount the application
code and data with read-only NFS and it's been a long time since
we've had any problems. (We had a lockups every six months, some
years ago, but those went away after some upgrade in '03 or '04.)
So if you just want to push data from a central location out to a
bunch of servers, NFS is worth considering.
