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!
