The upgrade instructions are in (info "(guix) Upgrading Guix").

I run the daemon on Debian but installed it with the install script, not
with the Debian package: I'm going to test the installation on a VM and
I'll see/document what a user should do to upgrade a daemon installed
that way

My /etc/systemd/system/guix-daemon.service is:

--8<---------------cut here---------------start------------->8---

# This is a "service unit file" for the systemd init system to launch
# 'guix-daemon'.  Drop it in /etc/systemd/system or similar to have
# 'guix-daemon' automatically started.

I tweaked it a little bit to add "--substitute-urls" to ExecStart and
"LC_ALL" to Environment, but the Guix provided one should work.

AFAIU following the official daemon upgrade instructions should do the
job: right?

If this is not the case with the Debian package IMO it's a Debian
package (.service file) bug: we should add a footnote to (info "(guix)
Upgrading Guix") and file a bug upstream if needed, no?

IMO the instructions on (info "(guix) Upgrading Guix") are clear; they
are just for a systemd based distro but should be easily "transposed" to
a different init system by the users... or not?

Thanks! Gio'
