iptables (started before network) will not find its modules in /usr/lib/iptables when /usr is NFS mounted.
Actually iptables isn't started anywhere at all because it's supposed to be used with kernel 2.4 only. Do you mean ipchains?
No, I'm meaning iptables. (I know it isn't used in the current release by RH-scripts, but it is contained on the CD and does not work if it is called like ipchains (startposition 08 before network)). If using a kernel 2.4, e.g. `iptables -j LOG' fails because it needs /usr/lib/iptables/libipt_LOG.so which is contained on a NFS volume.
With using kernel 2.4 in RH 7.1 this bug becomes important...
Fixed in 1.2.0-1
