Expected vs actual behavior

Trying to install RPM package that sets some udev rules in /etc and getting following error: $rpm-ostree install pylon-6.1.1.19861-1.x86_64.rpm error: Importing package 'pylon': Analyzing /etc: Unsupported path; see https://github.com/projectatomic/rpm-ostree/issues/233

The referenced issue goes about problems when RPM writes into /opt that apparently have been resolved. But It is unclear why RPM is not allowed to write into /etc and how /etc is supposed to be populated then?

Thanks for the report. Default configuration files shipped under /etc should be automatically moved to /usr/etc, but there is likely something going wrong with this specific package. Could you maybe share the specfile and the resulting RPM file for this pylon package?

Ah, I think this is complaining about the /etc directory itself. I'm not sure why this should be a special behavior for this specific package, but indeed I think this is hitting a case which rpm-ostree is not handling properly. We generally translate /etc/* to /usr/etc/* but it seems we are not really handling the plain /etc case: https://github.com/coreos/rpm-ostree/blob/df478a093f611c4553acafafb953a1ee49814f8f/rust/src/utils.rs#L267-L276

I'm not sure if shipping /etc directly in the package will result in a file conflict with other packages down the road, but we should probably fix our own path translation logic to begin with.

Thanks for the quick response and the info. It could be that there is a problem with the package, it it an alien converted package from Basler Pylon camera driver .deb package. So I guess I will have to repackage this manually.
