[Fedora-packaging] RPM Group vs. Sugar

Hi, the Sugar activity guidelines http://fedoraproject.org/wiki/Packaging:SugarActivityGuidelines#Sample_SPEC instruct using Sugar/Activities as the RPM Group. Is using non-standard RPM groups in Fedora really allowed? The Creating Package HOWTO suggests that it is not, although AFAIK no guideline actually states anything about it. Of course, RPM groups are not very meaningful anymore as comps are used... -- Jussi Lehtola Fedora Project Contributor jussilehtola(a)fedoraproject.org
