Hi,
I’m using a modular machine configuration, i.e. the scheme file returning the
operating system definition imports several other custom modules with service
definitions etc in the same directory. This does not work well with unattended
upgrades. The attached patch allows adding search paths to the unattended
upgrade service. I’m not sure this is the best solution though. Maybe the
preferred way to add these modules is to a custom channel?
The second patch changes the default channels to #f, i.e. the system default
(/etc/guix/channels.scm), which feels more natural to me.
Cheers,
Lars

Did you see (info "(guix) Unattended Upgrades"):
There are cases, though, where referring to
‘/run/current-system/configuration.scm’ is not enough, for
instance because that file refers to extra files (SSH public
keys, extra configuration files, etc.) via ‘local-file’ and
similar constructs. For those cases, we recommend something
along these lines:
(unattended-upgrade-configuration
(operating-system-file
(file-append (local-file "." "config-dir" #:recursive? #t)
"/config.scm")))
The effect here is to import all of the current directory into
the store, and to refer to ‘config.scm’ within that directory.
Therefore, uses of ‘local-file’ within ‘config.scm’ will work
as expected. *Note G-Expressions::, for information about
‘local-file’ and ‘file-append’.
I can see several options:
1. Use the trick above and add (say):
(add-to-load-path (dirname (current-filename)))
in your config file. Not pretty.
2. Turn your modules into a channel. Nice because there’s no need for
a special case, modules are automatically updated at each upgrade,
etc., but OTOH requires more paperwork.
3. What you propose. Easy to use but a bit low-level and users could
be tempted to pass local file names instead of using ‘local-file’,
in which case the process becomes more brittle (depends on things
outside the store).

I prefer being explicit here and keep ‘unattended-upgrade-configuration’
self-contained (/etc/guix/channels.scm could be modified behind our
back).
WDYT?
Thanks,

yes, saw it, but I wasn’t sure how to load modules from that directory. And I
agree, it’s not pretty, but probably better than option 3, because everything
is in the store.

I feel this might be the best option and I’ll give it a try.

Okay, I can see that, but I’d like to use the same list of channels in that
service and channels.scm. Since creating an etc-service for
/etc/guix/channels.scm does not work, I was left with the other option, i.e.
using that file for unattended upgrades. Are there any other options?
Cheers,
Lars

I’d say that specifying the ‘channels’ field of
‘unattended-upgrade-configuration’ gives you that, no?
Also, what doesn’t it work to populate /etc/guix/channels.scm via
‘etc-service-type’?
Thanks,
Ludo’.

no, /etc/guix/channels.scm also functions as a default channel list for every
users’ `guix pull`, which I also want to have.

This snippet:
---snip---
(simple-service 'guix-channels etc-service-type
(list `("guix/channels.scm" , (scheme-file "channels.scm" %guix-channels))))
---snap---
Causes this error when reconfiguring:

/gnu/store/mdpbph8cpgwydy3hwfq0q6sk44bfbk93-etc looks correct to me, i.e. it
has a guix subdirectory with a correct channels.scm file in it.
Cheers,
Lars

Yes, somebody else reported that problem recently (and proposed a
solution I think, was it on guix-devel?). The issue here is that
/etc/guix is also partly stateful, so there’s ‘activation-service-type’,
‘etc-service-type’, and manual changes say to /etc/guix/machines.scm,
are conflicting.

I’ve implemented this now and it is indeed a very good solution. For anyone
stumbling on this issue, I’m using the following service configuration:
---snip---
(unattended-upgrade-configuration
(channels #~(cons* (channel
(name 'psychnotebook-deploy)
(url "https://github.com/leibniz-psychology/psychnotebook-deploy.git")
(introduction
(make-channel-introduction
"02ae8f9f647ab9650bc9211e728841931f25792c"
(openpgp-fingerprint
"CA4F 8CF4 37D7 478F DA05 5FD4 4213 7701 1A37 8446"))))
%default-channels))
(operating-system-file
(scheme-file "config.scm"
#~(@ (zpid machines yamunanagar os) yamunanagar-os)))
(schedule "55 13 * * *")
(services-to-restart '(nginx ntpd guix-publish ssh-daemon mcron)))
---snap---
So, I’m fine with closing this as wontfix.
Cheers,
Lars
