Perhaps what happens is this:

- brltty 4.4 installed and running, but keeps failing to find a braille
  device since you don't have one, but that does not fill logs very much.
- the brltty package gets upgraded, but we don't restart brltty on
  upgrade.
- brltty 4.4 is thus still running, but the braille drivers have been
  upgraded, and thus can't be loaded
-> fills log

I guess a not-too-bad fix for this is to make this kind of loop much
less noisy, as less as the failing-to-find-braille-device loop?
