It should be added to the cost of the change. (yet another thing we ignored in this process). My experience has so far been very bad with systemd so when Lennart proclaims that everything's fine, I'm just filled with more worry. I'm trying to figure out how to prevent this in the future so we stop losing users. (Yes, we really are at pre-FC6 numbers wrt user base which means we have the fewest number of users since we started keeping track of such things) and I think it's because of poorly planned "features" like these. -Mike -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
