Rickard, can you take a look at this?

What do you think the errors come from?

It looks like portmap hasn't started. In your logs, I can't see it
happening, but maybe portmap is just quiet. However, I can't see much
network interface startup activity either, and portmap has startOn =
"started network-interfaces", so maybe that's the problem? Is
network-interfaces started?

Thinking about it, both statd and idmapd do "ensure portmap" in their

logs somewhere?

pre-start scripts, so portmap should have been started. Can we see portmap

Running rpc.statd in the foreground I get this error:

$ sudo rpc.statd -Fd

I noticed that I had this error on my system too. statd just keeps restarting. After I bit of googling I found this: http://forum.paldo.org/index.php?action=topic&topicnr=725&pagenr=1

Apparantely this is some combination of the later nfs-utils and portmap. Switching to rpcbind solves the problem. That is also the reason I didn't see this before, because I ran rpcbind and switched back to portmap. I've attached two patches, one for nixpkgs and one for nixos, that builds rpcbind and creates an upstart job for it. It also replaces the use of portmap in statd and idmapd. It doesn't remove portmap, but we should probably not keep both of them around.
