[BusyBox] pivot_root - devfs: how about "mount --move"?

[Roberto De Leo]

Hi again,
I noticed right now that the mount command has a nice "--move" option 
that can move a mounted fs to wherever you want.
I already tried with a devfs-ed /dev and it works!
This may be a solution for the pivot_root - devfs problem, but I noticed 
that unfortunately that option is not supported by the busybox mount 
:-(   [of course, life is never simple...]
Is there any hope to see it implemented? I have no idea if it is doable 
and/or simple to do and/or scheduled.
Thanks,
 Roberto De Leo
