The only changes that should be needed (though I haven't tested it to be 100% certain), is to update the required kernel to make sure it builds against the proper kernel and also bump the Release field in the spec from 53 to 54 to get a new NVR. Change line 4 %define spec_release 53 To: %define spec_release 54 Change line 9 %define kmod_kernel_version 4.18.0-80.10.1.el8_0 To: %define kmod_kernel_version 4.18.0-144.el8 > > -- > Brian Stinson > _______________________________________________ > CentOS-devel mailing list > CentOS-devel at centos.org > https://lists.centos.org/mailman/listinfo/centos-devel Thanks, Andy Walsh
