No, I didn't.

The Upstream Vendor has already switched to Koji and
it makes no sense to feed a full-blown software with
a long rat tail of another software that will blast
my embedded machines (which also uses mock for building
software native (a lot of packages needs that)).

CentOS is still using mock I see and this is a really
good tool. I'm also going to make it work for Minix-3
(and also RPM and rpmbuild). So I have to deal with
Python, again. It seems that apt-get support wants also
to get in ...
