Hi Hartmut,

The Guix equivalent is =E2=80=9Cguix pull && guix package -u=E2=80=9D.

However, as you note, this is per-user here: it only upgrades packages
of the profile of the user that runs it.

This is a deliberate choice: we want users to be able to manage their
own package set by themselves.  Thus=E2=80=A6

=E2=80=A6 upgrading packages of all users is not a central use case.  :-)

You *could* force each user=E2=80=99s ~/.config/guix/latest symlink to poin=
t to,
say, ~root/.config/guix/latest, and have a policy that only root runs
=E2=80=9Cguix pull=E2=80=9D.  That way, all the users would be using the sa=
me Guix.

But users would still be able to bypass it, and that=E2=80=99s the whole po=
int
of Guix anyway.

What do you mean by =E2=80=9Csystem binaries=E2=80=9D?  On GuixSD, system-w=
ide binaries
(which are under /run/current-system/profile/) are upgraded by:

  # guix pull && guix system reconfigure config.scm

HTH!
