I'm currently using kickstart for installing new servers and have run into the following scenario: all the machines will have the same basic setup of packages, however they will each be configured for a specific task. For example, some will be mail-serving machines and won't need things like a web or mySQL server installed. Others will be web servers and do need those packages. So my question is, is there some way do determine via kickstart, what to install on that machine based on some criteria, possibly the IP that's being assigned to it, or MAC address, or something ... Right now I have one single kickstart setup that all the machines are going to use, then I manually install the additional packages one by one, on each machine. It would be helpful if I can somehow tell kickstart to do that. Suggestions?
