When a user runs emacs (or any other program that uses fontconfig), a
cache is created in ~/.cache/fontconfig. This cache is not updated
automatically after installing new fonts, and must be manually cleared
out.

I guess this might be related to our use of Jan 1, 1970 as the
timestamps for all files in /gnu/store (which includes user profiles).

We should either modify fontconfig to detect a stale cache using a
method that works on Guix, or else notify the user that they must clear
the cache after installing ttf fonts.

Hello, I believe this issue had been fixed by:

commit 6f12880a76a6c91058718d15845f8b9d9b529a5a
Author: Sarah Morgensen <iskarian@mgsn.dev>

gnu: fontconfig: Use (locally) deterministic caching
Make fontconfig use directory contents rather than modification time to
determine cache validity (by pretending that mtime is broken).

Closing.
