[Fontconfig] [PATCH] Make the cache filenames determinstic

[Chris Lamb]

Dear Keith et al.,

Thank you for providing this explanation. However, one thing that
isn't clear to me is what the difference is between the (eg.) /var/
cache/fontconfig/21328251-11eb-4cba-b230-50d60512f1c8-le64.cache-7
files and the "/var/cache/fontconfig/.uuid" (or ".uuid") files?

Sorry if this seems obvious from the outside; I am simply not well-
versed in fontconfig lore.

(FYI: I'm all for removing these files, but please bear in mind I'm
coming from a somewhat one-track "reproducibility" point of view and
somewhat from a time-sensitive view of ensuring this is in Debian
buster...)


Best wishes,
