Eelco Dolstra 2c1ecf8e81 nix-env -i: Add a flag ‘--remove-all’ / ‘-r’ ... This is equivalent to running ‘nix-env -e '*'’ first, except that it happens in a single transaction. Thus, ‘nix-env -i pkgs...’ replaces the profile with the specified set of packages. The main motivation is to support declarative package management (similar to environment.systemPackages in NixOS). That is, if you have a specification ‘profile.nix’ like this: with import <nixpkgs> {}; [ thunderbird geeqie ... ] then after any change to ‘profile.nix’, you can run: $ nix-env -f profile.nix -ir to update the profile to match the specification. (Without the ‘-r’ flag, if you remove a package from ‘profile.nix’, it won't be removed from the actual profile.) Suggested by @zefhemel.		2013-09-03 21:21:14 +02:00
