I prepared a patch for nfs-utils 1.2.8-9 that adds a systemd drop-in for
nfs-common at 
/lib/systemd/system/nfs-common.service.d/remote-fs-pre.conf.
It places the nfs-common service before the remote-fs-pre target. This
results in the rpc.gssd service beeing started before NFS shares are
mounted during the boot process.

The patch is tested on my system and works for me. I suggest to upload
nfs packages with this patch to Jessie (through stable-proposed-updates)
in order to fix auto-mounting Kerberos-secured NFS mounts at boot in
Jessie.

Do nfs-utils maintainers take care of this upload? Otherwise I can do
the upload (and ask RMs for approval first) myself. A short comment
would be helpful.

Cheers,
