[bug#61483] [PATCH 0/5] Some basic Home Shepherd Services

[Jan (janneke) Nieuwenhuizen]

From: "Janneke Nieuwenhuizen" <janneke@gnu.org>

Hi!

I've been waiting for Guix Home to offer some basic shepherd services for most
used daemons, replacing the neat shepherd hack described in

    https://guix.gnu.org/en/blog/2020/gnu-shepherd-user-services/

that I've been using, and am a bit puzzled as to why this didn't happen.  Are
people using Guix Home?

Anyway, here's my attempt to address this, adding ssh-agent, git-daemon, and
also the probably less-used kodi and znc that I use on my home server.

To add a git-daemon and ssh-agent to your guix home profile, you need
a home-configuration.scm that has something like this:

--8<---------------cut here---------------start------------->8---
(use-modules (gnu home)
             (gnu home services shells)
             (gnu home services shepherd)
             (gnu home services shepherd-xyz)
             (gnu packages)
             (gnu packages base)
             (gnu services)
             (guix gexp))

(services
 (list (service home-shepherd-service-type)
       (service home-git-daemon-service-type)
       (service home-ssh-agent-service-type)))
--8<---------------cut here---------------end--------------->8---

The weird thing is that after running

    ./pre-inst-env guix home reconfigure home-configuration.scm

the shepherd starts automatically, starting ssh-agent and git-daemon.  Upon a
fresh login, however, it seems the shepherd must still be started manually,
kind of defeating its purpose as a home service...

Thoughts?

Greetings,
Janneke

[bug#61483] [PATCH 1/5] DRAFT gnu: home: services: Add home-git-daemon-service-type.

[Bruno Victal]

Hi,

Have you tried using (non-home) git-daemon-service-type as a home service?
I think it should work.


Cheers,
Bruno

Okay, after playing with this some more using a clean account all seems
to work fine.  Apparently there was some weird interaction with my
current shepherd-service setup interacted.

Greetings,

Yeah, I tried

--8<---------------cut here---------------start------------->8---
(use-modules (gnu services version-control))
;; [..]
,@(let ((root (string-append (getenv "HOME") "/git-daemon")))
    (if (not (file-exists? root)) '()
        `(,(service
            git-daemon-service-type
            (git-daemon-configuration
             (base-path root)
             (export-all? #t))))))
--8<---------------cut here---------------end--------------->8---

and upon guix home reconfigure I got

    guix home: error: no target of type 'account' for service 'git-daemon'

> I think it should work.

It might, and that would be nice, but I would need some more guidance as
to handle the account setup thing?

Greetings,
Janneke

Howdy!

I am!  :-)

Possible reasons not all the services described there made it into Guix
Home: (1) needs vary :-), (2) it’s possible to migrate incrementally,
with some things handled with Home while others are still managed “the
old way” (that’s what I do), and (3) rde is kinda “competing” with Home
by providing a whole bunch of services, giving less of an incentive to
migrate them (it’s an unfortunate issue we identified at the time Home
got merged).

But with contributions like these, the situation will improve!

I have a prototype here to “transform” a System service into a Home
service.  Would it be of any use here, to share code with
‘git-daemon-service-type’?

Looks like the only issue would be #:user "git-daemon", which is not
going to work, and I don’t have a good solution to that.  :-/

I’d make it ‘messaging.scm’.

With that an entry in the manual, it will be ready to go!

Rather in ‘ssh.scm’ IMO.

“Install and configure @command{ssh-agent} as a Shepherd service.”

With these changes and an entry in the manual, we’re all set!

Maybe something like: “Install and configure the Kodi media center so
that it runs as a Shepherd service.”

Likewise: this + manual entry and we’re all set IMO!

Oooh, I totally overlooked this.

Overall I’d suggest documenting in the patch that adds the service.
That way, each change is self-contained, which facilitates review, etc.

I would suggest creating one section per type, roughly corresponding to
the (gnu home services …) module: “Media”, “Version Control”, etc.  For
SSH there’s already “Secure Shell”.

Also please start each service’s documentation with a couple of
sentences giving context and possibly an example, similar to what’s done
for the existing Home services.

Could you send an updated patch series, maybe leaving out git-daemon
until we figure out whether/how to factorize it?

Thank you!

...but indeed.  I tried something along those lines.  Oh well, I guess I
can run my shepherd home git-daemon to system scope and we can ponder on
this some more.

Come to think of it, are there any plans/ideas to specify home service
configurations in the system configuration?

Greetings,
Janneke

Oh, good.  I'v been tempted for quite a while and will try to switch
when this patch series goes in.  I'll be moving bits the
executable/configuration bits (that are without secrets) from my
home.git to guix-home.

yeah...could be I'm the only one using kodi and znc, but I expected
ssh-agent to be kinda popular...

That sounds like a stategy I'll be following too

Ouch, why that's...terrible?  Is there any reason stuff is not
contributed "up stream"? ;)

> But with contributions like these, the situation will improve!

Yay!  Let's go for that, then.

Maybe we should automate that by having ‘home-ssh-agent-service-type’
extend ‘home-environment-variables-service-type’?  That way it’d work
out-of-the-box regardless of the shell being used.

Thanks,

Please also add the new file to ‘po/guix/POTFILES.in’ so descriptions
can be translated.  Otherwise LGTM!

In the meantime I realized I don’t have to push it on your behalf, so
I’ll let you take care of it—sorry for the confusion!

Thank you,

Oh that's a neat idea!  Someone will have to figure out how to do that,
later.

Well, it seems I added a dependency to the shepherd, module (shepherd
support), for things like

    %user-runtime-dir

I locally applied the attached patch to add Shepherd as an input (not
sure if that would be OK), but now `make update-guix-package' fails:

--8<---------------cut here---------------start------------->8---
$ make update-guix-package
git rev-parse HEAD

   "`git rev-parse HEAD`"
error: Failed to find the origin git remote.
make: *** [Makefile:7178: update-guix-package] Error 1
--8<---------------cut here---------------end--------------->8---

Not sure what to do, possibly best to revert the home services patches
again until we have (consensus on a) fix.

Greetings,
Janneke

I pushed a fix as be7e2bf7ebc10bb4e5808ddeabc4b914f575865f, tested with
‘guix home container’.

> I locally applied the attached patch to add Shepherd as an input (not

Guix in general on the “host side” should not depend on the Shepherd,
there’s no reason to do so.

The solution for Home or System services is to depend on the Shepherd
but only in the run-time code stage.  This is what I did in
be7e2bf7ebc10bb4e5808ddeabc4b914f575865f: code that needs to refer to
‘%user-runtime-dir’ is staged such that it will look up that variable at
run time, when the user ‘shepherd’ process is started.

That’s really what we want here, because it also ensures that the code
sees the right value for ‘%user-runtime-dir’ (otherwise it would see the
configuration-time value, which could be different).

Apologies for overlooking that!

Ludo’.

I've pushed the attached patch to take care of this.  Pretty neat!

Closing this bug now, if we want to address the git-daemon "transform"
and #:user "git-daemon" issue better to open a new bug report.

Greetings,
Janneke

Well, I also failed to see that I pulled in the Shepherd as a dependency
until sarg "complained" about a missing file on IRC.  Simply copied this
from my direct Shepherd solution, ugh.  Sorry!
