No. I was thinking on another program which lived inside the chroot and
was called to copy files outside.

I begin to wonder why you need to do so, though. Why do you chroot to a
folder if you then need to move the files anywhere else? What's your use
case?
If it's a simple drop box, you could use a unchrooted process watching
the folder and moving out new files.
