Comment 14 for bug 1758402

All user home directories are automounted and the mount options are identical between users.

The problem with attributing this to NFS in general is that it does appear to work most of the time. I mean, I have always seen occasional kactivitymanagerd crashes, and I've never been motivated to dig into them, but only these three users it crashes in a tight loop; new instances spawn and crash immediately and more instances are spawned in their place which crash immediately and so on. So much so that the machines get quite slow from all of the IO writing core files to the journal. It wouldn't be so problematic if it just crashed at login and stayed dead.

Really, NFS should be fine. The only instances where you're going to run into problems is when you're trying to do concurrent writes on an NFS implementation where locking doesn't work. The Linux NFS client and server together should support what sqlite needs, and in case there's no concurrency involved because there is access from only one client. And in any case, Firefox certainly doesn't have any problems with it and it uses sqlite rather extensively.
