I hope I'm posting this in the right place. I'm currently taking a course utilizing Fedora 16 in preparation to do the CompTIA Linux+ cert. I have set up Fedora in Hyper-V and I'm having some issues. In particular I'm trying to edit the /etc/selinux/config file and I'm unable to as the file says it is read-only. My user is part of the "wheel group" which as I understand it means I am an administrator. What do I have to do to be able to edit this file successfully? I am a total Linux Noob, any help would be appreciated.
