Hmm, I don't believe so. It was a temporary network glitch (damn flaky distribution switch) and the user wasn't able to login via xdm (his home directory was on the NFS partition in question). > > I personally think the non-blocking behavior is better. > > In some cases, yes, in some cases, no.

Heck, I don't even need the distinction between net and local, just critical would do. All remote, critical filesystems would be blocking, and all others not.
