Draft for not - I'm waiting for confirmation that the logfile doesn't log passwords or secrets.

Congratulations! One of the builds has completed. 🍾

You can install the built RPMs by following these steps:

• sudo yum install -y dnf-plugins-core on RHEL 8
• sudo dnf install -y dnf-plugins-core on Fedora
• dnf copr enable packit/sosreport-sos-3864
• And now you can install the packages.

Please note that the RPMs should be used only in a testing environment.

I think there could be more stuff that could be useful from a cephadm installations which may not necessarily trigger with packages. I know for certain there's been some discussions here around cephadm.

Not for the PR, but maybe for a future work we may want to add to sos in general.
