From 6266c5d32f9ff651fcfc3a4cc0c68e89da56ca65 Mon Sep 17 00:00:00 2001
From: Griffin Smith <grfn@gws.fyi>

Subject: refactor(users/glittershark): Rename to grfn

Rename my //users directory and all places that refer to glittershark to
grfn, including nix references and documentation.

This may require some extra attention inside of gerrit's database after
it lands to allow me to actually push things.
