[Grml] nfs-kernel-server wouldn't upgrade

I've installed grml to harddisk. I ran 'aptitude upgrade' and the recent nfs-kernel-server upgrade hung while trying to start nfsd. Running

/etc/init.d/portmap start

and restarting the upgrade fixed the problem.

I don't remember turning off portmap in /etc/runlevel.conf, but maybe I or bastille-firewall did.
