Description: Guided Exercise: Selecting the Boot Target (ch10s02)

While this change is a little more involved, I don't think that it would be too difficult and it would certainly be more beneficial if a student makes a mistake in /etc/fstab.

1. Rather than booting to rescue.target, boot to emergency.target.
2. Change the mount command to "mount | grep /dev/vda1" and highlight that the root file system is mounted read only in emergency.target.
3. Add a step to show how to remount / as read write: mount -o remount,rw /
4. As part of that step, you might tell students that they would need to do this if they had made a mistake to /etc/fstab and wanted to edit the file. Without remounting the root file system as read write, even the root user cannot save changes made to /etc/fstab.
