I have been using this option: system.copySystemConfiguration = true; Placing the current config "closer" to /etc/nixos/configuration.nix makes it easier to run diff against the active profile. copySystemConfiguration's location makes it easier to dig older profiles. Maybe it's a good idea to use both locations? > On Mon, Mar 30, 2015 at 4:10 PM, Michael Raskin <[email protected]> wrote: > > >On Mon, Mar 30, 2015 at 9:47 PM, Ryan Trinkle <[email protected]> > > > > wrote: > > >> On a somewhat related note, is there any way to see the exact > > >> configuration.nix for a particular generation?
