# pulseaudio is trash and insists on using machine-id as a prefix for
# its database filenames under ~/.config/pulse.  So, on systems with
# randomized machine-ids like Devuan GNU/Linux it shits the bed and
# can't find its own database files.  So we do its job for it and
# rename its database files on each boot.  Ditto for libcanberra's
# event sound cache database.
