1 The solution
==============
I managed to do it. I'll share some relevant information for those
interested.
[This section] in the Info manual helped me do what I was looking
for. As specified in that part of the manual, I need to edit
guix-daemon.service. In my system, there were 4 files with that name
(see code block below)
,----
| rdrg@desktop:~$ locate -r 'guix-daemon.service$'
| /etc/systemd/system/multi-user.target.wants/guix-daemon.service
| /run/systemd/units/invocation:guix-daemon.service
| /usr/lib/systemd/system/guix-daemon.service
|
/var/lib/systemd/deb-systemd-helper-enabled/multi-user.target.wants/guix-daemon.service
`----
The file `/run/systemd/units/invocation:guix-daemon.service' was a
broken symbolic link (see code block below), so I knew that I
shouldn't edit this file.
,----
| rdrg@desktop:~$ file /run/systemd/units/invocation:guix-daemon.service
| /run/systemd/units/invocation:guix-daemon.service: broken symbolic
link to 8dbd9f7458e74f979a2b8d214ed47d42
`----
The file
`/var/lib/systemd/deb-systemd-helper-enabled/multi-user.target.wants/guix-daemon.service'
wsa empty (see code block below), so I knew that I shouldn't edit this
file.
,----
| rdrg@desktop:~$ file
/var/lib/systemd/deb-systemd-helper-enabled/multi-user.target.wants/guix-daemon.service
|
/var/lib/systemd/deb-systemd-helper-enabled/multi-user.target.wants/guix-daemon.service:
empty
`----
The file
`/etc/systemd/system/multi-user.target.wants/guix-daemon.service' was
a symbolic link to `/usr/lib/systemd/system/guix-daemon.service' and,
for that reason, I ended up editing
`/usr/lib/systemd/system/guix-daemon.service'. I edited the line
containing `ExecStart' and added the IP address of my system from
which I wanted to retrieve the packages.
,----
| rdrg@desktop:~$ cat /usr/lib/systemd/system/guix-daemon.service
| # 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.
|
| [Unit]
| Description=Build daemon for GNU Guix
|
| [Service]
| ExecStart=/usr/bin/guix-daemon --build-users-group=_guixbuild
--substitute-urls='http://192.168.1.39:8080 https://ci.guix.gnu.org
https://bordeaux.guix.gnu.org'
| Environment=LC_ALL=C.UTF-8
| StandardOutput=syslog
| StandardError=syslog
|
| # Work around a nasty systemd ‘feature’ that kills the entire process tree
| # (including the daemon!) if any child, such as cc1plus, runs out of memory.
| OOMPolicy=continue
|
| # Despite the name, this is rate-limited: a broken daemon will
eventually fail.
| Restart=always
|
| # See <https://lists.gnu.org/archive/html/guix-devel/2016-04/msg00608.html>.
| # Some package builds (for example, go@1.8.1) may require even more than
| # 1024 tasks.
| TasksMax=8192
|
| [Install]
| WantedBy=multi-user.target
`----
Finally, I executed the following two commands.
,----
| systemctl daemon-reload
| systemctl restart guix-daemon.service
`----
When I executed `guix home', the packages were retrieved from my other
system (see line below `substitute: updating substitutes from
'http://192.168.1.39:8080'... 100.0%').
,----
| rdrg@desktop:~$ guix home -L ~/guix-packages reconfigure
~/guix-config/home-configuration.scm
| hint: Consider installing the `glibc-locales' package and defining
`GUIX_LOCPATH', along these lines:
|
| guix install glibc-locales
| export GUIX_LOCPATH="$HOME/.guix-profile/lib/locale"
|
| See the "Application Setup" section in the manual, for more info.
|
| guix home: warning: cannot determine provenance for current system
| substitute: updating substitutes from 'http://192.168.1.39:8080'... 100.0%
| substitute: updating substitutes from 'https://ci.guix.gnu.org'... 100.0%
| substitute: updating substitutes from
'https://bordeaux.guix.gnu.org'... 100.0%
| The following derivations will be built:
| /gnu/store/kdlm30fl3cv6r0ww2njm0d7w8cipjpyj-home.drv
| /gnu/store/76835anafmiz8ngx2aqwynps72m0wmgd-setup-environment.drv
| (... some omitted lines ...)

2 Pending question
==================
I was able to download packages from my other system without having
to perform the following step which is mentioned in [the
aforementioned part of the manual].
,----
| guix archive --authorize < key.pub
`----
I wonder whether this command is relevant in this context or not. Any
information is appreciated.
