These patches should canonically be in the source.puri.sm repositories:


For example, here is a patch of mine to Gimp:

These parts of "negative space" are less obvious. Whilst you mention
the absense of the non-free repository we also have removed other
specific packages from "main". I am unsure how to canonically generate
such a list from our archive software, but it is likely possible with
some grep-dctrl foo and a quick refresher on set theory.

In addition, there is the delta in unmodified packages that we have
migrated from unstable, which additionally add to the delta from
Debian buster. This could be a refinement othe programming task
outlined in my previous paragraph if one was inclined to locate the
exact answer.

Can you elaborate on this, just out of interest? In particular, what
is specific about the CD system that I am perhaps missing?

Best wishes,
