FREEBSD RECOVERY
1. Restart the system.
2. At the boot: prompt, enter boot -s to enter Single User Mode.
3. When asked what shell to use, press the Enter key.
4. Because the root filesystem will be mounted read-only by default, you will need to remount it using the mount -ruw / command to give yourself read/write access.
5. Run mount -a to remount all filesystems specified in the /etc/fstab file.
6. Run passwd root to set a new root password.
7. Run exit to continue booting normally.
