I want to update my unofficial guix packages for Arch and Fedora to
0.13.0, but I found the systemd service files installed by guix 0.13.0
use /var/guix/profiles/per-user/root/guix-profile/bin/guix* instead of
/usr/bin/guix* in ExecStart=. The path /var/guix/profiles don't exist
on systems that don't have guix installed before, and users will have
to manually start guix-daemon and install guix with guix before they
can use the systemd service files. Is it possible to fix systemd
service files, so it can be easily used by packages in other
distributions?

I'm a little confused: is there a situation where Guix is not installed
but '/usr/bin/guix-daemon' exists?

The path '/var/guix/profiles/per-user/root/guix-profile/bin/guix-daemon'
is guaranteed to exist if you followed the instructions in Binary
Installation [0], which is, as far as I know, the most common way to
install Guix on other distros. So, I think this path is appropriate for
the basic service file we provide.

I think that, if you are packaging Guix for other distros, you should
provide your own service file. My experience is that each systemd-based
distro uses systemd's advanced features (e.g. process grouping and
resource limiting) in different ways. So, making your own service file,
in accordance with your distro's standards, will help Guix work in a way
that is more idiomatic to the host distro.

`mv var/guix /var/ && mv gnu/`

This can happen with source installation. 'make install' installs
/usr/bin/guix* but not /var/guix. /var/guix doesn't exist until
guix-daemon is started.

I think you mean that the systemd service files included in Guix are
only intended to be used with binary installation process. Do you mean
that using them with traditional 'make install' installation is not
supported?

Yes, I am packaging Guix for Arch and Fedora, and I use the systemd
service files provided by Guix in my packages since version 0.8.3. If
doing so is never supported, I can make my own service files like what I
did for version 0.6 to 0.8.2 and I think this bug can be closed.

I see. We discussed this use case previously, which led to the change
which caused your issue:


In short, we decided to break this for `make install` since we didn't
come up with a better solution at the time.

It's de facto unsupported, since it's not working :) But, I think we
should address this use case, since it is causing problems for
downstream packagers.

I do think you should look into tailoring a service file to those
systems; you might be able to provide Guix on those systems in a more
integrated or idiomatic way.

However, we also try to offer upstream service files in the packages
offered by Guix, so I'd like to find a way to support both the binary
installation and `make install` use cases simultaneously.

Unless somebody proposes a fix in the meantime, I'll look into this more
closely before the next release.

I updated my packages to install two systemd service files for
guix-daemon to allow users to choose between /usr/bin/guix-daemon and
/var/guix/profiles/per-user/root/guix-profile/bin/guix-daemon.

Is it possible to resolve it by providing a configure option to choose
between two versions of systemd service files, so guix binary tarballs
can use /var/guix/profiles but packages of other distributions can use
/usr/bin?
?
