To reduce the noise I'm trying to mount the NFS partitions on the
workstation itself. (With both iptables and selinux disabled)
No go.

$ rpm -qa | grep nfs-utils
nfs-utils-1.0.10-12.fc6.x86_64
nfs-utils-lib-1.0.8-7.2.x86_64

As far as I could see, NFS was updated close to a month ago.
However, the machine got rebooted two days ago (Which restarted the NFS
daemon) - which in-turn broke the NFS configuration.
