Raspberry baby steps

Slowly moving over some simple services from main power hungry server to raspberry mini-server. Target situation would be that the main server is offline most of the day and is only powered up when I am actually home or in need of hefty services (power up on magicpacket).

Step 1 is done: Basic installation, DHCP, DNS and NTP. Next step would be web and mail services. Not sure how to design that one. Maybe keep mail (zarafa) running on main server, but cache incoming mail on raspberry. Maybe move web interface from apache to nginx if zarafa web interface works with that setup. That is something for next weekend.
