The chroot requirement is specified because a non-isolated build is
worth nothing: it might work on some machine and fail on another one for
hard-to-find reasons.

We could stop mentioning it if we think everyone keeps chroot enabled
(that’s probably the case), but it doesn’t hurt to keep it.

Well yes, that’s the thing.  For i586-gnu we’re currently stuck because
we haven’t yet defined how to normalize the build environment:

  https://guix.gnu.org/en/blog/2020/childhurds-and-substitutes/
  https://issues.guix.gnu.org/43857

And it’s not theoretical: some util-linux tests may or may not work
depending on whether the Hurd box has /proc set up, the Texinfo test
suite would pass if there happens to be a usable ‘pt_chown’ program
around (see <https://issues.guix.gnu.org/59616>), etc.

So I think the current situation is that we can build base packages for
i586-gnu, that’s fine, but don’t have a solid foundation like we do on
GNU/Linux, so there’s no point in going too far.

Now, I don’t think the i586-gnu situation is an important consideration
for the commit policy.
