We need a mapping for “localhost”, otherwise (for instance) X apps fail:

_X11TransSocketINETConnect() can’t get address for localhost:6010: Name or service not known

/etc/hosts is not enough, a /etc/nsswitch.conf with the following line is needed:

hosts: files dns

(This was never a problem in the cs.uu.nl domain because there is a localhost.cs.uu.nl in DNS.)
