If total RAM is less than 512 MB (for example, the minimum 256 MB RAM requirement), KDE (kdm) is not started.
If rads_minimum_ram=100000 (100000 MB) you will not get headless. Or not able to boot. Can you drop down to a Virtual Console and edit /etc/rads.d/ folder ?
For a text console: Press Alt + Crtl + F1.
For additional text consoles: Press Alt + Crtl + F2 or F3 and so on.
For a graphical console: Press Alt + Crtl + F7.
My plan was to raise the min ram requirements to a high
level so it would never boot KDE> > Is there a better way to do this?
rads_start_display_manager=0
Setting rads_minimum_ram to some crazy value to reach that goal I
would consider a hack. I would wouldn’t like having to tell users to do
such things. I try to avoid such cumbersomeness. rads_start_display_manager=0 is the setting you want.
