I followed the steps in the document, but I was asked to give the root password.
Here is what I did:
1. On the Grub menu type e
2. Append rd.break to the end of the line starting with linux
3. Hit Ctrl+x
It boots to this:
Give root password for maintenance
(or press Control-D to continue):_
Any tips, please!?
I'm not sure what you mean by "changed"... Those are the instructions that have been used since RHEL 7.0.
They will not work for RHEL 9.0
They will work for RHEL 8.x, 9.1, and 9.2.
