To do so:

1. Cut previous branch of distgit repo to create the <release>-rdo branch
   e.g: https://review.rdoproject.org/r/c/config/+/52518
2. Edit SPEC file
   e.g: https://review.rdoproject.org/r/c/rdo-infra/rdo-release/+/45805
3. Trigger CBS build

   # First build the SRPM and trigger a scratch build to test it
   $ cbs build --scratch --wait cloud9s-openstack-zed-el9s rdo-release-zed-1.el9s.src.rpm
   

   # If the scratch build is successful then trigger the final build
   $ cbs add-pkg cloud9s-openstack-zed-candidate --owner rdobuilder rdo-release
   $ cbs build --wait cloud9s-openstack-zed-el9s rdo-release-zed-1.el9s.src.rpm
   

1. Create the redirects in www.rdoproject.org to point to the cbs builds both for rdo-release-bobcat and rdo-release-2023.2. Examples in https://softwarefactory-project.io/r/c/software-factory/sf-infra/+/28587 and https://softwarefactory-project.io/r/c/software-factory/sf-infra/+/29060
2. Check if the RPM is available

   $ curl -L -o /dev/null https://rdoproject.org/repos/openstack-bobcat/rdo-release-bobcat.el9s.rpm
   $ curl -L -o /dev/null https://rdoproject.org/repos/openstack-2023.2/rdo-release-2023.2.el9s.rpm
