Installing from SL 8 and upgrading does work, but SL 8 is an old sabayon. I `ll be building some iso `s soon. I would like to hear your suggestions, as I can`t build a version with every desktop environment. Should it be a small core cd like cdx or something lite, such as with, say, lxde? Also, which spinbase should I use, probably SL 8 with a newer kernel included or SL 10?
