Hello,

While preparing the 0.15 release I realized that ‘guix pack --bootstrap’
had become ineffective.  Concretely, ‘tests/guix-pack.sh’ would attempt
to build the world.

This is a consequence of c45477d2a1a651485feede20fe0f3d15aec48b39, which
introduced a dependency on guile-sqlite3 in derivations that build
packs, even if they don’t actually produce a ‘db.sqlite’ file in there.

I started looking for solutions, which led me to the patch below.
That’s quite intrusive and it doesn’t work because then we have a
similar issue with (guix hash) trying to dlopen libgcrypt.

I’m not sure how to best address it.  Another approach would be to do
away with ‘--bootstrap’ and instead write those tests as “system tests”
in a VM, though that’s maybe less satisfactory.

Thoughts?

Thanks,
Ludo’.
