As it stands now exactly, none. I only checked one profile: default/linux/amd64/13.0/desktop/kde/ and that consists of one file - parent. It lists .. and targets/systemd as parents. Which is easy enough as long as the idea of systemd with kde stays exactly like that - the strict union of kde and systemd profiles. Right now, a few line script can create those profiles, will it always be that way? What are the chances of LXDE and/or XFCE getting their own profiles like Gnome and KDE? If they do, and they warrant a systemd sub-profile, then the number of updates increases quite a lot. I've seen this kind of thing happen many times where the number opf combinations quickly gets out of control and becomes scary maintenance. It's a pity Gentoo doesn't support multiple profiles (just keep enabling extra till you get what you want or portage finds a conflict). That would make new profile settings much easier. It's probably not supported for the same reason most languages don;t go multiple inheritance. Oh well >> Conceptually, it is rather similar to switching between nouveau and >> nvidia.

And that first line of code - relying on "-nvidia" being in /proc/cmdline - wtf is that? :-) Such, um, butcher hacks work OK on your machine but sure ain't production ready -- Alan McKinnon alan.mckin...@gmail.com
