STEP BY STEP:

1. Reboot the system.
2. Interrupt the boot loader countdown by pressing any key, except Enter.
3. Move the cursor to the kernel entry to boot.
4. Press e to edit the selected entry.
5. Move the cursor to the kernel command line (the line that starts with linux).
6. Append rd.break With that option, the system breaks just before the system hands control
from the initramfs to the actual system.(remove the "extra" console=ttyS0 lines if needed)
7. Press Ctrl+x to boot with the changes.


To reset the root password from this point, use the following procedure:
1. Remount /sysroot as read/write.
switch_root:/# mount -o remount,rw /sysroot
2. Switch into a chroot jail, where /sysroot is treated as the root of the file-system tree.
switch_root:/# chroot /sysroot
3. Set a new root password.
sh-4.4# passwd root
4. Make sure that all unlabeled files, including /etc/shadow at this point, get relabeled during
boot.
sh-4.4# touch /.autorelabel
5. Type exit twice. The first command exits the chroot jail, and the second command exits the
initramfs debug shell.
At this point, the system continues booting, performs a full SELinux relabel, and then reboots
again.
