When login, the sytems needs to look at all the groups to know in which groups
the user is. As long as NIS is enabled for groups the system will look at
it at login time, whichever order is specified in nsswitch.conf for group

I believe it'll wait for a server to reply, yes

I just set up a test nis domain on a domU. With default files in /etc it
came up without troubles.

Do you have NIS or DNS enabled for hosts in /etc/nsswitch.conf ? It could
be the cause of the hang. Especially if NIS is enabled and the hosts
involved in NIS startup aren't listed in /etc/hosts (with the proper names),
there will be a deadlock.
Are the hosts in the ypservers map and /var/yp/binding/<domain>.ypservers
properly recorded in /etc/hosts ?
