Not all 32 bit ioctls are implemented as wrapper to ioctls in 64 bits.

This will work if -i parameter is add to mount in rc.sysinit. The mount 
-i does not call in this case to mount.aufs, just use mount. Maybe we 
can keep a overlay copy of rc.sysinit or ...(*)

Anyway: I said that remouting / as ro (aufs) is not necessary. This is 
only necessary when you boot a normal filesystem with rw (normally will 
be mounted as ro), so in the next step can run fsck.

* Maybe can be implemented without any issues in rc.sysinit at initscripts.
