For example I have the media keys setup to use mpc and wanted to also control the fans, disply and keyboard brightness.
After a bit of searching I came across this blog post using a bash script.
It has been a few weeks since I did the install so I am not sure if I used autopart or custom.
But I ended up with a LUKS encrypted xfs filesystem that boots when you hold down the option key. You can do this in Anaconda by selecting a basic desktop on the left side of software selection and LXDE and Xmonad on the right side.
