I got some questions on the test itself.

How could I run this test?
As I see, the #:export is missing, so I couldn't run it with the make
check-system.
Sorry, I am kind of a newcomer to the Guile world - I see the call of
the %test-foreign-install in the end of the file, but how should I run
the whole file?

Somehow I got some out of memory errors a couple of times during the
qcow build with this configuration
- so I changed to the following and stopped encountering this issue (odd
that 256 MB is not enough here sometimes):

On this step I see, that guile reports that source files are newer than go
files and starts recompilation.
Probably, that is because of updated timestamps when copying.
Looks like it could be fixed with the keep-mtime? set to true.

After that test installs guix on debian, but during the build of
hello it starts building all the dependencies, which is unexpected, I
think, and fails during the fetching of sources (which is, probably,
expected, because the network is not available).

Sorry for the inconvenience, I still figuring out how it works (or
should work).
