Yes, Etoys is precisely a version of Squeak with more objects added in.

More objects written in Squeak.

Explain to John and me how you get a command line in Etoys. No, I see
it. It's the text input mode in a Scriptor.

http://www.fit.vutbr.cz/study/courses/OMP/public/software/sqcdrom2/Tutorials/SqOnlineBook_(SOB)/englisch/sqk/sqk00046.htm

tells you how to operate the controls to get to a scriptor and type in
it to create a changes file.

doFileout
Smalltalk changes fileOut.
self beep: 'croak'

Actually, John, everything you need is in the Etoys Help tool--Script
Tiles, Object Catalog, and Halo Handles (including the Viewer and
Debugger)--and the Squeak tutorial

Is this .sources output what Debian is asking for? If not, why not,
and what would we have to do to complete it from their point of view?

Smalltalk condenseSources
extracts the currently valid definitions form both
the sources file and the changes file and merges these into an
new sources file SourcesV3.6 (you are asked to supply the name of the
new sources file).
All outdated definitions are dropped. We have a 14MBytes sources and
10 MBytes changes file.
When these merge we have a 16 MBytes source file and a nearly empty
changes file. We therefore conclude, that the 10 MBytes of the changes
contained 2 MBytes new code and 8 MBytes development history.

Can gst bring in a .sources file and a .changes file and create a working image?

Yeah, it's mostly Smalltalk source and objects created in Smalltalk.
