Hi all,

Thanks for the info. I like the way user shepherd services work so far. I haven’t used it much yet but it seems to mostly do the trick. The only thing I want is the declarative configuration. By “declarative” I mean configured in config.scm. Do you think there could be a chance of adding a services field to the user record type to create a corresponding Shepherd init.scm for user level shepherd services?

You can use shepherd and herd commands (without sudo).
For example:
$ shepherd [-c config.scm]
$ herd status

Then configure your `config.scm` as you like. As a default shepherd will use `$XDG_CONFIG_HOME/shepherd/init.scm`, and if the variable is not set then `$HOME/.config/shepherd/init.scm`.

That can be done by generating a text-file in store containing the desired config then symbolic linking it to `$HOME.config/shepherd/init.scm`. This all can be done using guix daemon(declaratively).

Though I am not sure how you can 'autostart' the service at boot time and declaratively?

Thanks Chris,

I wasn’t aware of the autostart spec so I took a look. Thanks! After reading it I’m not sure it provides the retry support (among other things) that a user service might provide. I would love to see something closer to an event triggered service than forking once and forgetting.

It would be awesome if the Guix System could provide a way to configure these declaratively, too. I am not saying shepherd would be the mechanism, necessarily either. I just think people - myself included - will probably want this feature. 

Thanks again,

John

Hi Reza,

I’m not sure this is possible right now. I recently tried making a
service which would need the x display variable and I got stuck right
about when I needed the logged in user. I would love to see it though.

Does anyone else know?

I don't think there's an easy solution that's integrated into the Guix
System (formerly known as GuixSD).  Instead, the best approach is to use
any of "the usual" methods for starting up user processes.  For example,
you might use the ~/.config/autostart convention:
