Hi Rodion,

Oops, I ran it with:

  ./pre-inst-env guix build -f gnu/tests/foreign.scm

but really, it should have exported the test so one can run:

  make check-system TESTS=debian-install

I’ll fix that in a second version.

Interesting; it worked for me.  But perhaps that has to do with the
timestamp issue: if .scm files were being recompiled due to timestamps,
then the process ended up consuming more memory.

Yes, that’s a good idea.  I guess I was just lucky the .scm timestamps
looked older than .go timestamps.

‘%installation-tarball-manifest’ is so that only ‘hello’ itself is
missing from the store.  If you observe that it tries to build more,
then something is wrong; looking at the “The following derivations will
be built” message can (maybe) give a hint, by looking at the bottom of
that long derivation list.

Thanks for taking a look, I’ll send a new version fixing these issues!
