We should probably always re-apply all options from fstab. Also /proc,
/dev, /dev/shm which we mount natively with systemd may have options
listed in fstab, which might need to be applied later. There are
setups with insane amounts of disks which can't reliably bootup
without the proper non-default options for the /dev tmpfs.

So a common way to do this mandatory task would be good to have, I think.
