It doesn't usually take that long, but the first `guix pull` is quite slow, and what should be a no-op of running it a second time immediately afterwards also takes too long.

Edit: Just to provide a measurement, on my Framework 13 with AMD Ryzen 5 7640U, a `guix pull` which pulled in 1 nonguix commit and 64 guix commits took 2m10s, and a subsequent no-op `guix pull` took 1m18s.
