nix-channel improvements "nix-channel --add" now accepts a second argument: the channel name. This allows channels to have a nicer name than (say) nixpkgs_unstable. If no name is given, it defaults to the last component of the URL (with "-unstable" or "-stable" removed). Also, channels are now stored in a profile (/nix/var/nix/profiles/per-user/$USER/channels). One advantage of this is that it allows rollbacks (e.g. if "nix-channel --update" gives an undesirable update). 2012-04-14 18:38:52 +02:00			`system = builtins.currentSystem;`
