The comment states "crimson: centos8 centos9" but the actual FLAVOR parameter is just "crimson" without the "centos8" qualifier. This is inconsistent with the actual build configuration in line 141 which only specifies centos9. The comment should be updated to match the actual configuration: "# crimson: centos9".

Suggested change

	# crimson: centos8 centos9
