Replace ubi9 image for ubi-minimal to reduce footprint

[oglok]

This could be a good start to reduce image size as reported in #152

Minor comments.

This is a minor patch, but I think it's quite a bad practice in open source communities to work on top of other contributor's PR without any consultation. I don't mind about this particular one, but it is very discouraging.

My apologies @oglok and thanks for the feedback. The intent was to push it forward so it can be merged (and the suggestions were, IMO, minor and required corrections in comments).
However, will refrain from it in the future.
Would you suggest that both suggestions and rebasing, in general, are left to the original author?

The mode of operation should be discussed at the llm-d governance level, or per project, and it's whatever we agree. For merging PRs, it could be just one core reviewer approval, or two core reviewer approvals. In general, unless a group of people is working on a big feature which can be co-authors of the commits, a PR is pushed, reviewed, and the author/owner of the PR is the one to address those comments, or discuss them in case there is a reason behind the logic of the PR.
Open source mode of operation might seem to slow things down, but it allows people to reach consensus and create better projects.

@elevran – Just a quick note for future PRs: unless a change is truly time-critical and can't wait, it's generally best practice to let the original author address review comments. It gives them a chance to respond, learn from the feedback, and decide whether they agree with the suggested changes. It's also a more courteous approach that helps foster a positive and collaborative environment. Rewriting someone’s contribution without their involvement can discourage future contributions, which we definitely want to avoid.
