[Spacewalk-list] Configuration Files Deployment + Remote Command on Action Chain

True, I get the point,
I managed to do something similar by deploying configuration files (scripts aclually) with a configuration channel. The chalange however is that you want the client to act on this. In short I found two way to do this.
First a script can be developed that is ran every period of time (by cronjob). make sure that the deployed files only run once when it gets deployed. You can remove the file or log the script in a file and detect a script has ran before and skip it. I use a script that detects when a script has been (re-)deployed (by timestamp) and runs it once. It will re-run the script when it gets re-deployed.
the second alternative, which in my opinion is a more neat one is to use inotify to detect when a file/directory changes. When something changes it should do an action (for example run it). This will allow instant run of scripts when they get (re-)deployed. Disadvantage of this is that the clients need to run an extra daemon to detect file/directory changes.
For single time actions I use SSM and remote command. Foor more often actions I use the script (part of a defaul config channel) that is a cronjob (every 5 mins).
Hope this helps.

Hi rick,
Yes, it can be easily handled by remote command, but the question is.
Action chain is only temporary for a scheduled action only. And, action
chain couldn't be saved with configuration files.
So I must create a new chain, if I want to deploy the selected files.
And yes you're right, it can be done only using remote command and use
sed, select the correct systems. But, you will need much time to do that.
CMIIW.
