Well, the initramfs should mount the rootfs readonly, and then it can
read it's /etc/fstab (and the /forcefsck file) and determine if any
further action should be taken before doing any kind of pivotroot type
stuff to transition to the host OS. This should all be handled by your
initramfs really. Not sure what systemd bits do that in a systemd+dracut
combo tho', as not fiddled with it for a while!
