Nitpicking: index entries are usually lower-case.

Perhaps add:

  @xref{Invoking guix pull}, for more information.

What about restating upfront that we’re talking about foreign distros
specifically:

  On a foreign distro, you can upgrade the build daemon by running:

  @example
  sudo -i guix pull
  @end example

  @noindent
  followed by (assuming your distro uses the systemd service management
  tool):

  @example
  systemctl restart guix-daemon.service
  @end example

  On Guix System, upgrading the daemon is achieved by reconfiguring the
  system (@pxref{Invoking guix system, @code{guix system reconfigure}}).

?

Feel free to push something along these lines.

Thank you,
Ludo’.
