The best thing to do would be to occasionally boot the older system to update 
it.

SE Linux controls all aspects of system security, including global thing such 
as mounting file systems and directly writing to block devices.  If the 
chroot had a local policy as you suggest then which policy would control 
writing to the device node for the boot device?

Something like Xen is what you need.  The below URL about Xen and hypervisor
