This repository has no description
configs: allocate uids dynamically, drop stockholm.lib
pairprogramming, radio, realwallpaper and the htgen users no longer get
their ids from stockholm's genid. NixOS keeps the ids existing users
already have in /etc/passwd and /etc/group, so nothing changes on
deployed machines; fresh installs allocate them.
The copied htgen, reaktor2 and realwallpaper modules use nixpkgs option
types instead of stockholm's, htgen's user is a small name/home
submodule (home still defaults to /home/<name>), and reaktor2 carries
its own stripAttr.
