Systemd by default mounts it with autofs, it will not be mounted until
it is accessed, which does not happen during normal operation. We
currently miss autofs timeout handling, which would umount /boot again
when it is no longer used. That would make stuff pretty robust, I

are the norm and not the exception. We must mount it unconditionally,
