Previously, when I had installed GuixSD in my systems I executed "herd
discover guix-daemon on" in order to be able to retrieve packages from
my local network and thus reduce the download time.

Now, I'm installing Guix on a foreign distro and I want to enable server
discovery in my local network in this system. Because it is a foreign
distro, there's no herd command. I'm wondering if it is possible to
accomplish the same result as "herd discover guix-daemon on" in a
foreign distro.

Any help is appreciated.

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

  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%').

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.

With regards to the pending question which I mentioned in my previous
message, I think I have found the answer.

The system where I was installing the foreign distro showed a big list
of packages to build. However, after I run the following command, that
list was greatly reduced, so I suppose that the following command allows
retrieving built derivations from other systems which makes it
unnecessary to build those derivations again.

A cleaner way to do this is to run `sudo systemctl edit guix-daemon.service`.
It will open your editor to create a drop-in override file, in this case
/etc/systemd/system/guix-daemon.service.d/override.conf, with a commented-out
version of the base unit file included. You'll want to write something like this:

```
[Service]
ExecStart= 
ExecStart=/usr/bin/guix-daemon \
    --build-users-group=_guixbuild \
    --discover=yes \
    --substitute-urls='https://bordeaux-us-east-mirror.cbaines.net https://bordeaux.guix.gnu.org https://ci.guix.gnu.org'
```

The most confusing part is that you need two ExecStart lines, one unsetting the
old value and one setting your new value.

Ooops, it seems that I didn't include the command in my previous
message. This is the command I was referring to
