Got it installed and running, apart from all the 503 errors and the problems with thunderbird, it is working relatively effortlessly.
on the other hand it is _very_ GREEN ... hmm, that's a bit better.
It took a long time, and a large number of tries (I started at 8:30 this morning and it was finished by 4 in the afternoon ... and it reckoned it was only 550Mb worth of download)
Will probably comment more later.
Ok, It's not faster than the OpenSolaris ... and the keyboard defaulted to US-English ...
svc:> select svc:/system/keymap:default
keymap/layout astring US-English
svc:/system/keymap:default> setprop keymap/layout=UK-English
everything else seems to be working with the new branding and all.
