  • I feel kind of bad about this but I refuse to join Guix IRC. I use mailing list out of frustration but these communication channels are the proof that Guix is not only a nice, useful and open project but it has born a project for fossbro babyboomers. It is a golden walled garden for themselves , I don’t feel ok in that space.

    EDIT: I’ve answered a little emotionally. Let me clarify, I believe most Guix maintainers act of of good will and they want to find some communication platform which is inclusive for everyone (since it is clear also to rocks that IRC is good only for someone born before 1990, so it is good for people aged >= 35) . Some of the maintainers, and some most noisy members of the community make it so bad for everyone else but themselves that, having so much explicit and soft power, the discussion about moving away from communication protocols older than CDs was closed stating “everything is perfect as it is, we reach exactly the right set of people, we do not care of increasing the userbase or making the community more inclusive”.



  • Would be pretty useful, as far as I know there is no way to change /etc/{subuid,subgid} in the system configuration without manually editing.

    Well I had to make one :) it is being tracked on https://issues.guix.gnu.org/72337 . You can define subuid and subgid ranges like so:

    (use-modules (gnu system shadow)      ;for 'subids-service-type'
                             (gnu system accounts))   ;for 'subid-range'
    
    (operating-system
      (services
        (list
          (simple-service 'alice-bob-subids
                          subids-service-type
                          (subids-extension
                            (subgids
                             (list
                              (subid-range (name "alice"))))
                            (subuids
                             (list
                              (subid-range (name "alice"))
                              (subid-range (name "bob")
                                           (start 100700)))))))))
    
    

    which would yield

    # cat /etc/subgid
    root:100000:65536
    alice:165536:65536
    
    
    # cat /etc/subuid
    root:100000:700
    bob:100700:65536
    alice:166236:65536
    

    Another annoyance with podman on guix is making / a shared mount doesn’t work so changes in mounts aren’t propagated.

    I think I solved that by using a Shepherd service run on boot calling mount --make-shared / . I didn’t do extensive testing of mounts but I’m currently using this on my systems as it’s set up in my personal channel. By adding the following to my own system config

    (use-modules (small-guix system accounts)
                             (small-guix services containers))
    
    (service iptables-service-type)
    (service rootless-podman-service-type
                   (rootless-podman-configuration
                    (subgids
                     (list (subid-range (name "alice"))))
                    (subuids
                     (list (subid-range (name "alice"))))))
    

    I’m able to run the following rootless Podman hello world

    $ podman run -it --rm docker.io/alpine cat /etc/*release*
    NAME="Alpine Linux"
    ID=alpine
    VERSION_ID=3.20.2
    PRETTY_NAME="Alpine Linux v3.20"
    HOME_URL="https://alpinelinux.org/"
    BUG_REPORT_URL="https://gitlab.alpinelinux.org/alpine/aports/-/issues"
    

    and with guix shell podman-compose I’m able to run this Podman compose hello world:

    $ mkdir data
    $ echo hello world > data/index.html
    $ podman compose up -d
    
    ...
    
    exit code: 0
    $ curl localhost:8080
    hello world
    

    So some kind of mount appears to work. Thank you for your feedback and feel free to try the service from my own channel if you are interested in providing more or in trying rootless podman on the Guix System.




  • I wouldn’t go the manual way if you are not forced. If you use NetworkManager you can import the configuration either grafically or with nmcli.

    It should be sufficiente to modify the network manager service provided by Guix:

    (modify-services %desktop-services
     [...]
     (network-manager-service-type config =>
     		               (network-manager-configuration
    			        (inherit config)
    			        (vpn-plugins (list network-manager-openvpn))))
    

    reconfiguring your system, rebooting and then importing the configuration and set your credentials






  • imho having a more accessible contribution workflow would increase the number of people interested in spending time in reviewing.

    Regardless of the many problems of web forges today the ability to review only what’s changed between the various revisions of a pull request and the comments in a single view is not achievable with a simple email workflow. You end up reimplementing the PR/MR functionality with other tools, exactly as is happening with the Guix QA tools. I love them but we’re reimplementing gitlab/gitea/codeberg by parsing patch revisions from emails subjects.
