A quick scan through shows no updates related to FP in the few weeks
preceeding that (quite few arm64 updates at all really). This all seems
to match the pattern I mentioned when this was originally reported - it
does happen sometimes but there's some very thin race or something which
means it only comes up *very* rarely. None of which is helpful for
figuring out what's going on :/
