I went through the whole guide and have just rebooted successfully!!!
Now I have all the stability, power, and bleeding-edge-ness of Gentoo, with the wonderful, gorgeous-ness of Sabayon!!
Thank you for writing this up so well wolfden
. I wouldn't recommend this process for someone new to linux, or who doesn't fully understand portage, but I'd also say that this process is quite manageable for someone who is prepared to think through each step, read error messages thoroughly, and who has good google-skills.
PS: I have been left with some error from revdep-rebuild relating to gnucash. I think this is cos I unmerged gnucash (it wouldn't emerge and I don't use it), and it left behind a lot of libraries it doesn't need any more. I've also got a dbus_daemon error message, but I'm off to hit google to figure that one out!
