finishing a week of teaching a comptia linux+ class off of centos 7.4 and wanted to demo how to boot to "rescue" mode, so i rebooted, selected "rescue" mode at grub menu, which still booted to full multiuser, graphical mode. what am i doing wrong? or is this a dumb question?

$ yum info dracut-config-rescue
