Thanks!
$sources no longer exists in the suite scripts, it's too much of a
maintenance headache. Instead, emsource uses the apt-cross cache to work
out which source package provides the requested binary. The problem then
is removing the duplicates where the suite script needs only two of many
binaries built from one source package to prevent emsource having to
build the same source twice.

You could use the apt-cross cache here, you should certainly not use the
main system cache. Otherwise you will miss packages where Emdebian makes
a new package split. e.g. debconf does not provide debconf-shell in the
main Debian apt cache, only in the Emdebian cache. True, this is only
because of the bug in cdebconf but still, debconf-shell is needed to
actually get an emsandbox package set that can be installed as cdebconf
cannot be used without the Emdebian debconf-shell package (at least
until the cdebconf bug is fixed).

You just need to work with the apt cache from the Emdebian repository,
not the Debian mirrors and get your showsrc from that.

The example was just that - a beginning. Thanks for working on it.

man reprepro
Don't generate the tree manually, do it with reprepro and make it easy
to maintain.

You need to run edos-debcheck against it too so you'll need Packages.gz,
Release etc. i.e. a normal apt mirror. reprepro runs the Emdebian
repositories and the scripts all expect that level of support so it's
best to use reprepro so that you don't get surprises from debootstrap.
