✅ Formalities

• I have reviewed the CONTRIBUTING.md file for detailed contributing guidelines.

If your PR contains a patch:

• It can be applied using git am
• It has been refreshed to avoid offsets, fuzzes, etc., using

  make package/<your-package>/refresh V=s

• It is structured in a way that it is potentially upstreamable
  _{(e.g., subject line, commit description, etc.)
  We must try to upstream patches to reduce maintenance burden.}

@neheb Could you take a look at it, please?

[neheb]

Package syslog-ng is missing dependencies for the following libraries:
libcap.so.2

[BKPepe]

Thanks for testing, @neheb. I do have minimal build on my machine, thus that is why I have not experienced it. I will disable it. :)

btw there seems to be some whitespace. My editor did this:

Might as well update to 4.10.2.

[BKPepe]

Sure - #27684

[BKPepe]

At this point, it appears that syslog-ng requires dependencies even though it shouldn't, because the features that require them are disabled. Therefore, to prevent merging, I'm putting this on hold until this issue is resolved.

[BKPepe]

Ivykis dependency will be added in separate PR - #27717
