CentOS Stream 9 has been around for a while, but it was officially announced just a few days ago. I already tested some earlier snapshots and they had some rough edges. The current version installed without random crashes, has networking and runs smoothly. EPEL – the semi-official repository by Fedora maintainers – is already there, but practically empty, syslog-ng or it’s dependencies are not yet there. As someone asked about syslog-ng support, I had a first try at building it.
I built syslog-ng for CentOS Stream 9 in the Copr build service. Many of the syslog-ng dependencies are not yet available, so I had to compile them myself. EPEL 9 is expected to have the latest Fedora versions, so I used those. I could not get MongoDB client libraries compiled, but the rest of the dependencies are there.
