Date: Fri, 19 Jan 2024 15:12:13 +0100

Hoping to upstream this nice service from RDE. This service allows to
embed a home environment in a operating-system declaration.

This would be much welcome!

Could you add a header similar to that found in other files?

Since this is copied from rde, make sure to preserve their copyright
notices.

In Guix we’d use ‘match’ instead of ‘car’ + ‘cdr’:

  https://guix.gnu.org/manual/devel/en/html_node/Data-Types-and-Pattern-Matching.html

But perhaps we could just as well define a <guix-home-configuration>
record or similar?

> +(define (guix-home-gc-roots config)
> +  (map cdr config))

Unused.

> +(define guix-home-service-type
> +  (service-type
> +   (name 'guix-home)
> +   (description "Setups home-environments specified in the value.")

“Sets up Guix Home for the specified user accounts.”

> +   ;; (compose append)

Why comment it out?

Also make sure to register the file in ‘gnu/local.mk’.

Last, we usually require a test for system services; you can find them
in gnu/tests/*.scm.  Could you try and write one?  It would check for
instance that the user’s shepherd is indeed started.

Could you send an updated patch?

Thanks,
Ludo’.

Hi all,

I accidentally submitted a patch very similar to this one at
https://issues.guix.gnu.org/69781. FYI in case anyone winds up iterating
on this version of the patch.

Not sure how to merge debbugs issues. I did implement most of the
feedback mentioned in this issue and resolved a couple of other
problems.

Oops indeed.  Lars, I’m closing this issue, but please let us know if
you have suggestions!
