Again, from my experience -H allows for successful run against 300+
hosts, so it's not a problem, especially when the host list is
provided by a shell script which takes that list from the database.
Speaking about urgency, you'd better not consider Cfengine as the
immediate tool (still from my experience). First, a runagent makes
nothing else than just invoking cf-agent on the other side, and the
cf-agent invoked will run through the whole policy set. It's not very
immediate. Next, runagent's backgrounding is screwed (or at least was
screwed in 3.0.5p1, didn't check the 3.1 yet). I made a patch which
allows real backgrounding with -b option, but I cannot remember now
whether did I submit the patch to Mark or left it for my own. Without
proper backgrounding, cf-runagent won't proceed with the next host
until it finishes with the current one. Even further from the urgency.
If you're using cf-runagent only for explicit things, you may define
certain classes in your promises which alter bundlesequence for agents
restricting it to the certain tasks, so that things will be certainly
speeded up. The process requires thorough design and testing, though.
