Kickstart snippet
 

I made certain change in kickstart snippet in redhat satellite server, basically the snippet is for rabbit- server (user, packages,sudo etc). I made changes and updated the snippet. I have more than 20 rabbit-servers. Now,want to deploy the changes that I made in kickstart snippet to all these server so that I can achieve what I have desired. Now, could you please tell me how can I do this?

Thank you so much in advance.

I'm not very familiar with Satellite and Spacewalk, so I may be off-base here, but Kickstart files are only used to handle installation of systems. If you want to change the configuration of already installed systems, you'd need a configuration management tool like Puppet, Chef, or cfEngine to make those changes.

Note that IIRC Satellite is a paid-for Red Hat product, so you should have Red Hat support on your installation. You should therefore talking to Red Hat support about the best way to do what you need.
