I agree that it's surely a mixture of different fuck-ups, but there is
no reason to make it easier for people to accidentally brick their
laptops. To the best of my knowledge, you can't brick your laptop by
unlinking any file in any other virtual filesystem. The most you can
get is a kernel panic, in a few very specific situations. You reboot
and you are fine. With UEFI is apparently a completely different
story, so users should have been told, IMHO.
