[arch-general] Mounting root according to fstab the first time (fstab in initrd)?

[Devon Smith]

According to this page:
http://www.freedesktop.org/software/systemd/man/systemd-remount-fs.service.html

The systemd remount service remounts your root file system according
to what is listed in fstab. This includes mounting root with the mount
options listed therein.

If you need something else, what exactly are you trying to do?
