- /etc/hosts aka /etc/inet/ipnodes: requires now the FQDN of the machine, e.g.
  10.0.0.10 foo foo.do.main
- /etc/nsswitch.conf: for 'hosts' and 'ipnodes' the db 'files' has to be
  at the first place - NOTFOUND=continue  UNAVAIL=continue do not matter
  anymore! E.g.:
  hosts: files nisplus dns

otherwise network/physical:default will fail and the machine is unreachable.

X11:
- remove /usr/X11/lib/X11/rgb from /etc/X11/xorg.conf
- remove everything in /var/dt/sdtlogin/ - otherwise dtgreet may not come up
  because of font loading problems
