* gnu/services/desktop.scm (%fontconfig-file-system,
fontconfig-file-system-service): New variables.
(%desktop-services): Add fontconfig-file-system-service.

months now without any problems. This adds it to %desktop-services.

What about something like:

  ;; The global fontconfig cache directory can sometimes contain stale
  ;; entries, possibly referencing fonts that have been GC’d, so mount
  ;; it read-only.

I think that’s a correct summary?  Perhaps we could link to past
discussions if we have one.

Otherwise LGTM, thank you!

I didn't find a canonical bug report but it was mentioned in several in
the past. I added references to two of them.
