Comment 8 for bug 607906

That's really strange. You can see below that it claims to mount the rootfs read only. But as you can also see, i can just create a file and that file is still there after reboot (so it's not just some strange ram cache i am seeing). And you can also see swap not being mounted.

I am pretty sure you don't need a real rootfs for this. An empty second partition should do fine.
