Ah, thanks. The MIRROR_DIRECTORY is outside chroot, correct? Will it get
wiped when building the iso?

hmm, when trying to answer the above questions using the UTSL method, I
noticed that it is not quite as what I proposed. 

- One has to build a (local) Debian mirror first before he is able to use
MIRROR_DIRECTORY and MIRROR_SOURCES. I haven't done that before.
Will I have to pull in the full Debian mirror, not just the
packages that I need? The bind mount method on the contrary, does not
require one to setup anything, and does not require storing any
unnecessary packages either.

- Using the MIRROR_DIRECTORY and MIRROR_SOURCES, grml-live still need to
download packages into the chroot, then wipe the downloaded before
building the iso. Even the mirror is local, there are still some quite
heavy disk RW going on. With bind mount and up to date local apt archive,
disk RW will be near-zero. Quite a performance boost, isn't it?
