Well. Will qemu still actually _run_ without glusterfs being present? If so, do we actually need to express a dependency on glusterfs? To me, the semantics of 'X requires Y' are fairly close to 'X will not function correctly without Y'. 'X can do some extra stuff if Y is present' does not seem to meet the case. -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | identi.ca: adamwfedora http://www.happyassassin.net -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
