From 7b7a8919b149bf094308aebc414e713a02bd400f Mon Sep 17 00:00:00 2001 From: sterni Date: Sun, 27 Feb 2022 16:36:38 +0100 Subject: [PATCH] feat(sterni/external): add flipdot-gschichtler We'll need this in depot in order to import my infra, as I run flipdot-gschichtler for the OpenLab at the moment. Importing the repository into the tree is not really an option, as it should stay in the GitHub organization. Additionally, it doesn't currently really have a license, but it is very possible it'll end up being AGPL. The whole thing is quite tame and has (anecdotically) never broken on a nixpkgs channel update. A new niv sources area is created to avoid cluttering the global one and having these sources in a gc root permanently.
