guix-daemon.service and guix-publish.service use deprecated StandardError/StandardOutput features

Both guix-daemon.service and guix-publish.service make use of

StandardError=syslog and StandardOutput=syslog.

When building a guix 1.2.0 or 1.3.0rc* on Debian, I get the following

warnings when checking with lintian:

W: guix: systemd-service-file-uses-deprecated-syslog-facility lib/systemd/system/guix-daemon.service StandardError=syslog

Following the above link has this to say:

* StandardError= and StandardOutput= in unit files no longer support

the "syslog" and "syslog-console" switches. They were long removed

from the documentation, but will now result in warnings when used,

and be converted to "journal" and "journal+console"

automatically.

So apparently need to switch the .service files to use "journal". I am

not sure what implications that would have for installing guix on a

foreign distro, such as minimum systemd version, or if anything needs

significant changes.

Presumably at some point support for this Standard*=syslog will be

dropped entirely from systemd...

Hi!

Vagrant Cascadian <vagrant@debian.org> skribis:

[...]

Could you confirm that setting those to “journal” works on Debian?

If it does, it’s probably safe now to make this change, so feel free to

commit it in Guix.

Thanks,

Ludo’.
