Reinstall

With issues building ON from source, and corruption in some of the base system packages (~500 pkgs as reported by pkgchk) I decided the easiest thing was to reinstall.

Quite quick to set up having done it once :). For users using DHCP, if opensolaris gives a hostname of "unknown" after reboot you need to poke the following files:
/etc/nodename -- your system hostname (the important one)
/etc/hostname. -- hostname for the interface
/etc/defaultdomain -- your domain
