Is this ok [y/N]: 
```

Is there any specific reason why container image builds do not set
`install_weak_deps=False`?

you can use fedora-minimal, which  is created without the weak deps.

 I have started to remove some of the not needed packages from the main base image but
feel free to open a pull request to https://pagure.io/fedora-kickstarts :-)

fedora-minimal uses microdnf so it is not desirable for many cases. And you really
don't need those weak deps in normal images either...

I mean, what is the point of pulling packages which are never used in containers?

* `python3-unbound` which works only when unbound is running (which is usually done via
systemd)
* `rpm-plugin-systemd-inhibit` which works only if you have systemd/logind running

I'm pretty sure other packages are useless in containers as well. My goal here is to
have working (and useful, whatever that means) small Fedora container images.

This is all fine with me, as I said in my previous comment feel free to open a PR to the
kickstarts repo.
I guess we can start by making this change in rawhide first.

@cverna oh, then I misunderstood you. Can you help me to find place where I can put
setting to not install weak deps?

Sure I think you just need to modify the following line
https://pagure.io/fedora-kickstarts/blob/master/f/fedora-container-base.k... to add
`--excludeWeakdeps`.

This is how it is done for the minimal image
