[cobbler] Some generic questions about Cobbler

Hi, I was able to get my installation (RHEL, plus an app) working with Cobbler, but there are some things I am not clear about: 1) The .ks file I was able to get working is in the /var/lib/cobbler/kickstarts directory, but I noticed that there is another file in that directory that has a .cfg file extension. What is that file for? 2) In the .ks file, I saw a variable (I think it's a variable) named "$continueAnyway". It looks like that sets whether the kickstart file should continue being processed. Is that a standard variable in Cobbler? How do it get set? Sorry, I know these are kind of vague questions, but I'm still puzzling my way through all of this :)!! Thanks, Jim
