Hello,
Commit 09e028f adds support for setuid binaries. Since the store cannot
contain setuid binaries, we use the same technique as NixOS: setuid
binaries are created when booting (or when switching configurations.)
That is, for each setuid program, a hard link or a copy of the
executable is created under /run/setuid-programs and make setuid-root.
You can test it by running:
./pre-inst-env guix system vm build-aux/hydra/demo-os.scm
and running for instance ‘ping’ as guest from there.

That's great news! I've been missing sudo lately.

But note that this won’t help when using Guix on another distro.
