Subject: [PATCH] nixos/system-path.nix: add 3 to every priority
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We can’t use lowPrio here because it erases the differences in
priority of the packages by setting it to a constant value. see this
comment for info:
