Unfortunately, it crashed the same way, almost on the same file:

```
tanguy@lime2:~$ time sudo guix system init --cores=1 /etc/config.scm /
# […]

```

I guess I can close this issue, for it’s not a problem with `guix pull` anymore.
And I don’t think being "RAM-hungry" is a bug… but more of a "feature". 😅

So…

… moving on to the next option: Offloading!
