Oh, I didn't realize that 'lb modify' isn't available yet. You
probably told me at the Connect that it needs implementing, but I must
have forgotten that and thought this fix was good to use.

So this should be changed to just running a generic script then by
just executing the file the user has supplied, would that be good
enough?

    sudo ${user-script} --chroot-path ${chroot_path}

I re-read Ricardo's comment now about adding two separate hooks and
that seems to be needed again. So we should be able to provide a
pre-hwpack-install script as well as a post-install script. Any other
options that we should pass to the hook scripts?
