Comment 6 for bug 46516

I've tried to debug this further, and I'm pretty sure that if-up.d/mountnfs isn't run at all when 'ifup -a' is run in rcS.d/S40networking:

Feb 2 16:06:25 rcS: * Starting portmap daemon... ESC[80G * Already running. ESC[80G ^MESC[74G[ OK ]

notice that I've put 'set -x' in the mountnfs -script, which is shown only when loopback is ifup'd.

This is with feisty. NFSv3 mounts somehow get mounted, but NFSv4+krb5i not.
