of course, need mkdir -p $MNTPOINT/var/cache/apt/archives beforehand.

Yes, that does make sense. 

However, I'm using grml-debootstrap to build a minimum system, thus I'm
incline to install the extra approx into both host and chroot environment,
just to eliminate a risk that is rather low. Furthermore, approx has a big
overhead, I don't want to pull in OCaml just for it.

I will never need to run 2 parallel grml-debootstraps or use apt-get in the
host system, so bind-mount is a more suitable solution for me, which does
not bring in any other extra dependencies.
