No problem. I hope I can help with it.

I want to remount a ext2 that is a constituent  of it. Not the unionfs itself. 
I have tried it with
mount -o loop ext2.img t1
mount -o loop squash.img t2
mount -t unionfs -o dirs=t1:t2 t3
mount -o remount,ro t1

and it works.

The problem is with the chroot that takes place during the boot.

What is the plan? End /init with a ro / and make /sbin/rc add /memory?

Before that I had a hack to gentoo linuxrc to use a ext2 root with links to a 
squashfs mount. Assuming that I can solve the remount problem, this will be a 
much cleaner solution with a smaller deviation from the gentoo scripts.
