I use nfs about twice/year to transfer large files between machines -- so
I'm quite an expert at praying to the computer gods to "please let this nfs
mount work just this one last time and I'll never bother you again, I promise!"

I'm lying, of course, because I intend to do it again six months from now.

Every time, the computer gods make me suffer through multiple attempts to
guess the correct magic prayer before the remote nfs filesystem finally
appears for its biannual visit on /mnt/nfs.

Yes, I may well be paranoid, but it seems to me that the magic prayer for
nfs mounts changes every time I need it.

Sometimes I succeed using mount.nfs4, sometimes using mount -t nfs -o
nfsvers=4, or sometimes just mount -t nfs.

I have NFI what the real secret is, so I ask you nfs wonks to have mercy
and fill us in...
