Indeed this is a big problem: Everything is first stored in the local store:
The linux source, the deblobbing scripts, the deblobbed linux-libre source,
and so on; including a copy of guix as well as a grafted copy of guix.
Deduplication should help a little, but it appears only at the end of the
build. And being too generous with "guix gc" risks wasting hours of
compilation time. Instead I should have been more generous and replaced the
old micro-SD card :)

Well, it had been working previously with Guix on Debian, but the Novena
support has improved so much over the years that I wanted to try the full
Guix experience. If I do not manage, I can still do a Guix on Debian...
