If only httpd-1.0-2 is installed and you do downgrade to httpd-1.0-1, then the triggerun will be executed which is what I do not expect because no httpd less then 1.0-2 can be uninstalled at the time. BTW I've pushed quota-1:4.00-2 to F17. This is the version doing the migration with triggerun. I print a message by the triggerun script, so you see it's run even when downgrading to 1:4.00-1. -- Petr -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
