I have a spec file that currently requires mysql packages. I now have a requirement to require either mysql or MariaDB. But, I'm not sure how to set up such an OR releationship in my .spec file. I am somewhat familiar with the virtual "Provides" piece, but I am not sure if these mysql and equivilant mariadb packages provide the same thing.
%if 0%{?build6}
Requires : mysql-server, mysql, ...
%endif
%if 0%{?build7}
Requires : mysql-community-server, mysql-community-client, ...
%endif
