Comment 5 for bug 765545

Actually, turns out that I still have the same problem using IPs instead of hostnames. I'm using these entries now:
192.168.0.70:/secure/alex /home/alex/secure nfs defaults,rw,exec,user,nobootwait 0 0
192.168.0.70:/data /home/alex/data nfs defaults,rw,exec,user,nobootwait 0 0

and the boot just prompted me again for the usual "S or M" input. Just for reference:
% nslookup nasi.local
Server: 192.168.0.1
Address: 192.168.0.1#53

Name: nasi.local
Address: 192.168.0.70
