DNF config-manager Plugin

[j-mracek]

Documentation if dnf4 command - https://dnf-plugins-core.readthedocs.io/en/latest/config_manager.html

I am proposing to not keep DNF4 compatibility, because the syntax was not the best one and we also have new requirements due to support of drop-in directories for configuration.

• Investigate options how to implement configuration overrides for main config

  • implemented in Add support for drop-in configuration directories  #813

• Investigate options how to implement configuration overrides for repositories

  • implemented in Add support for repos configuration overrides #820

• Implement mechanism to synchronize dnf and subscription-manager

• implement configuration management and repositories

  • Will be implemented in [dnf5] config-manager plugin #907

• Configuration of repositories could be handled by a different command that for main repositories (under repo command)

• missing feature in DNF4 - unable do dump repository configuration

  • Implementation of master configuration dump and repository configuration dump [dnf5] Implement new arguments "--dump-main-config", "--dump-repo-config=REPO_ID,..." #877. Unlike dnf4, it can be combined with any command - they are global dnf5 options, not part of config-manager.
  • In addition, dump of variables are implemented. [dnf5] Implement new argument "--dump-variables" #875. (missing in DNF4)

• --save option was somehow strange in DNF4

Additional inspiration for handling of drop-in configuration:
rpm-software-management/libdnf#1387
rpm-software-management/dnf#1414

I started a separate discussion about this, i.e. #422.

Issues reported by the lack of config-manager plugin here https://bodhi.fedoraproject.org/updates/FEDORA-2023-69dfac15db#comment-3063374

[msrb]

Fedora CI relies on the config-manager plugin as well:

Unknown argument "config-manager" for command "dnf5". Add "--help" for more information about the arguments.

Currently I use dnf-3 config-manager as a workaround in the meantime.

Thanks!

Is dnf-3 config-manager something we can expect to exist in Fedora 40+ (and later CentOS Stream, etc)? Or is it just a temporary workaround that might go away in the not so distant future?

@j-mracek hello, could you please help us,

Configuration of repositories could be handled by a different command that for main repositories (under repo command)

I checked this command. It cannot modify the repo: enable/disable. This command can only show info.

Automation is very important. Could you please give any ideas on how we can enable disable repos in an automated way (from bash script)?

Thank you in advance.

@Andrei-Stepanov it's not very pretty, but this is how I'm doing it in openQA:

sed -i -e "s,enabled=1,enabled=0,g" /etc/yum.repos.d/fedora-updates-testing.repo

replace with the appropriate repo file, of course.

Thank you @AdamWill for a workaround.

Seems like closed by mistake; shouldn't #907 close this one?

Thank you for notes
