Good, bind mounts are working, as I saw some older kernels don't listen to the read only on creation of the mount, and you have to remount as read only.
I tried that, but I got file busy...
It's working now though, so I hope the busy thing was just a coincidence.
We need it read only because, otherwise makexconfig will just keep recreating the xorg.conf.
And yes, nice to see, when rebooted, the upside down is gone, it boots up 'normally'

Oops... the boot screen/tree was normal... but now I'm in diags... ha
(It exited ok, system is fine now)
