My biggest doubt was whether this would make a system that previously did not use iscsid now suddenly start to require a service. But if I understood 'man systemd.unit' correctly, adding an 'After=' without a 'Wants=' or 'Requires=' is valid, and merely means that _if_ iscsid is enabled, then systemd will enforce the ordering, but that libvirtd will manage just fine even when iscsid is disabled. I'm not much of a systemd expert, so I'll wait until morning before pushing, to give anyone else a chance to disagree with my analysis or provide a more kosher fix. Otherwise, you have my ACK, and I think this deserves to be in 1.0.3. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
