It doesn't appear possible to remove the default Conflicts= just by
creating /etc/systemd/system/var.mount.

I tried doing my plan of adding a boolean to mount units if we detect
them at coldplug time, and ensuring we pass that from the dracut systemd
to the deserialized main pid.  But what I hit doing that was from
dracut-systemd's perspective it is /sysroot/var, and not /var.  Would
need to do some sort of device/inode pairing to fix up paths after a
potential switch-root.
