Ok, then let's try tmpfs for aufs xino files.
Assuming RHEL changes the root dir readwrite after fsck or something,
:::
mount -t ext3 /dev/hda1 /sysroot
mount --ro -t squashfs /dev/hda2 /sysroot/.mount
mount -t tmpfs tmpfs /sysroot/tmp
for i in bin lib sbin usr
do mount -t aufs -o xino=/sysroot/tmp/xino,br:/sysroot/$i:/sysroot/.mount/$i \
aufs /sysroot/$i
done
mount -o remount,ro /sysroot
:::
There is no changes necessary /etc/fstab, I think.
