Syntax of `dnf config-manager --setopt` about dnf-plugins-core HOT 3 CLOSED

Also, what dnf config-manager --setopt=proxy=example.com test (i.e. --set-opt without --save) do?

Hello, @korpe1.

What is the difference between dnf config-manager --save --setopt=test.proxy=example.com and dnf config-manager --save --setop=proxy=example.com test?

In this use case, I believe the behavior of both commands is the same. However, if you were to use an additional option, such as --set-enabled, the provided <section> argument would be passed to this option, resulting in a different behavior.

If " If not specified, the program will select the main section and each repoid used within any --setopt options. A repoid can be specified using globs." is true, does dnf config-manager --save --setopt=*.proxy=http://proxy.example.com:3128/ will change repo1, repo2 and main confs?

Hmm, I believe the documentation could be enhanced in this regard. Generally, it appears that mixing the repoid selector in the --setopt option with an explicit list of sections is not a good idea. The explicit list of sections (repos) takes precedence over the repoid selector. The main section is written only if no repoid in --setopt is used and the explicit section list contains the main section or is empty.

Therefore, your example modifies only repo1 and repo2.

Also, what dnf config-manager --setopt=proxy=example.com test (i.e. --set-opt without --save) do?

As the --setopt is a global option intended for setting temporary runtime configurations, the --save option was introduced to make these changes permanent without altering the global behavior by the config-manager plugin.

In your specific use case, setting proxy=example.com using --setopt without --save applies only for the duration of the config-manager command's runtime which is useless there. But, it can be useful, for instance, when inspecting the entire configuration before making permanent changes. You can achieve this by using a command like: dnf config-manager --setopt=zchunk=0 --dump.

I am closing this. Improving the documentation should be handled in the linked follow-up ticket.
