Linode Gentoo and OpenRC
I tried the upgrade on one of my two boxes at home. I had some difficulty because I had never run dispatch-conf before. Just as a warning you don't want to learn dispatch-conf during a critical upgrade, learn it when you are using a package that can be removed completely and not a package that will make the system unbootable if removed. Long story short, I learned how to use dispatch-conf the hard way. NOW I hove setup dispatch-conf to use RCS backups on my two home boxes and my Linode.
