[SPARCbook] changing domains/IP-addresses on the fly

If you want the changed hostname and IP address to work immediately,
you will need to not only change the files but also use `ifconfig` to change
the interface IP and netmask, use `route` to add and/or remove routes for
your new default route, and use `hostname` to change the hostame of the
machine.

You will still run into problems with services like NFS and printing with 
daemons that are still running from boot-up, but could probably
just use the existing rc scripts in /etc/rc2.d and /etc/rc3.d to stop
and start certain services, after changing the hostname.

I frequently plug my SPARCBook into various client networks, and just
ifconfig a new address, and add or remove routes as needed, but I'm not
using NFS, printing, or other services that would have broken with these
kinds of changes.  I also don't typically bother changing the files, since
I'm only wanting to use the new address and routes for the visit.

I'm very happy with 2.6 on the SPARCBook, just had to get used to not having
the NCE gui, though frankly I was never that thrilled with NCE anyway.
