vs.

zwinger.wikimedia.org:/home  /home  nfs  bg,soft,tcp,rsize=8192,wsize=8192,timeo=14,nfsvers=3 0 0

• use version 3! Version 2 breaks > 2GB file access in some cases.
• bg - system can boot without mounting it - will retry in background
• soft - return I/O error to caller on major NFS timeout instead of retrying indefinitely
• tcp - use tcp instead of the default of udp - Why? because this ?
• rsize, wsize of 8192 - better throughput (ike)

It seems that explicit version 2 breaks > 2GB file access, but implicit (default) version 2 does not. Need to do a bit more checking to see if it's not some of the other options causing it.
