Hi.  I was trying to build guile-gnutls via guix in a debian12
container, and the sequence below happened.  Is there a missing
dependency on daemonize?

/Simon

$ sudo podman run -it --rm --privileged debian:12-slim
# apt-get update
# apt-get install guix git
# git clone https://gitlab.com/gnutls/guile.git
# cd guile/
# guix build -f guix.scm

It is mentioned in /usr/share/doc/guix/README.Debian.

I am of mixed mind on doing more than that... with the debian defaults,
it is not needed, so it seems a bit much to add it to Depends or even
Recommends. Suggests is hardly used much, but might make it a little
more visible than the README.Debian?

I guess I could add:

  Recommends: systemd-somethingorother | daemonize

But I think recommends with | sometimes behave a little oddly...

Hi,

is it? I ran into the same issue and I did read guix.README.Debian which does
not cover this situation. There is a section called "Using with sysvinit" but
that does not apply here because no sysvinit is involved, right?
is already installed on most systems then adding a Depends on it does not hurt
because it will make no difference. On the other hand, very minimal systems
that do not have the package installed will benefit from such a dependency as
without it, the package cannot function.

It seems though that the situation has changed a bit now in 2024 and the guix
package is installing a native systemd service file which does not require the
daemonize tool anymore?

About systemd-sysusers: there is no policy requirement to add a dependency if
your package ships files in /usr/lib/sysusers.d in the same way as there is no
requirement to add a dependency on cron if the package ships a cronjob in
/etc/cron.d. Maybe as a datapoint, if src:guix were to run
dh_installsystemduser as part of the build, then it would add the following to
${misc:Depends}:

    systemd | systemd-standalone-sysusers | systemd-sysusers

Another thing to ask: is there a common-enough use-case with which the package
can be used without systemd-sysusers (or some of its real providers)?

Maybe similarly, if one does not have the package "netbase" installed, running
"guix pull" will fail with:

    guix substitute: warning: ci.guix.gnu.org: host not found: Servname not supported for ai_socktype

This is because without "netbase" the file /etc/services will not exist. So why
is the guix package not depending on "netbase"? You may also argue: any
reasonable system will have "netbase" installed (it is Priority: important
after all). But if that is so, then adding a dependency on netbase will not
hurt either, right? The package "netbase" is not marked as Essential:yes so if
using guix cannot reasonable by done without /etc/services then it should
depend on the package providing it, no? This is a similar argument as for
depending on systemd-sysusers in the way as it is done by dh_installsystemduser
above.

What do you think?

Thanks!

cheers, josch

In my experience I have never had this issue running systemd ... so I
did assume it was a sysvinit environment ... let me know what
environments this occurs in!

I did some basic testing with sysvinit that worked at the time to
resolve:

https://bugs.debian.org/983248

Which is why the README.Debian includes any instructions at all.  If
those instructions are insufficient due to changes or other environments
not covered... please clarify and ideally propose a tested, working fix!
:)

I do not think anything changed; the guix package in Debian has been
using systemd units from very early on (if not from the very
beginning); the systemd services do not require daemonize.

Honestly, I do not wrap my head around all these different permutations
of user and group instantiation. I have it working with a fairly
standard debian install, and if there is something specific, simple and
straightforward to make it work in other environments, I will not block
it outright...

It requires manually adding all the users and groups expected to be
available with the guix-daemon service, and perhaps manual configuration
of the guix-daemon service.

This is brought up in:

https://bugs.debian.org/1051829

I stalled out trying to find a reproducer of the issue that makes sense
(e.g. an environment with network access but netbase not installed), but
honestly, given the tiny size of the netbase package, I just went ahead
and added it to Depends just now...
