OK, that gave me 

S50resolvconf
S51network
S52network-up
S60nfs

now. But that does not change anything else or fix my problem.

as recent as can be:

---------CUT--------
% rpm -q initscripts resolvconf
initscripts-8.48-8mdv2007.1
resolvconf-1.37-3mdv2007.1
---------CUT--------

But after digging a bit deeper, I found this:

---------CUT--------
% ls --full-time /etc/resolv.conf 
-rw-r--r-- 2 root root 222 2007-02-06 15:15:21.706332226
+0100 /etc/resolv.conf
---------CUT--------

So resolv.conf was last modified on 15:15:21

however, /var/log/syslog logs the "host has non-inet addr" on 15:15:15

---------CUT--------
Feb  6 15:15:15 yamm exportfs[2310]: athene.example.com has non-inet
addr
---------CUT--------

This looks like exportfs was querying for athene.example.com on 15:15:15
before resolver information was present (15:15:21) and thus fails.

So this looks like exportfs does not wait until resolver information is
available.

Maybe a prcsys/init script issue?
