I just tested out the daily amd64_K image (dated May 11th, 2011). Installation went well, but when I logged in to my desktop for the first time, the first-run script tried to open the Sabayon homepage with Firefox. Chromium comes installed now instead of Firefox. I just got a small error pop-up window saying 'firefox' is an unknown command. I guess the first-run startup script needs to be changed to invoke Chromium instead of Firefox?
