RE: [Condor-users] Using condor to update condor

Kind of. I don't need the whole cluster to stop crunching, just each node. So when a node has downtime (or can be forced gracefully to have downtime) it updates it's binaries. What's an "admin level command"? Do you mean a condor-specific command or are you talking about something on Windows?

I agree with Matt Hope that there are plenty of ways to accomplish software updates on windows that cost money. I think we use LAN Desk here. It'd be nice if there was some rudimentary support for this in Condor. Sounds like no one is using Condor to try and accomplish anything like this though.
