I see the point to need this.
But I think that would be a too restricted scope.  IMHO.

It needs a bit reworking on how the last seconds of chroots are handled
(discarding the chroot/saving the chroot+(re)packing) before doing it,
but I'd rather add a hook meant to be run always when creating the
chroot.
After this would easy editing the chroot, because that would be as easy
as writing the script to do the changes, rather than creating costum
scripts and getting them executed inside somehow (as we do in
jenkins.d.n)
