I have been off doing other stuff and no time to work with arm systems and builds and my systems were just working fine until...

First discovered no sudo. I always had used su and never noticed no sudo. Is there someway someone could send me the bin and I could run it from a usb drive from my user account?

But since no sudo, I wanted to boot into single user mode to change root's password. I hook up to the console serial port and power cycle the server. I get a selection list of

Centos Options
1:        centos

No way to up arrow and press A to append single mode to that.

How do I get the system to boot into single mode?

thanks

Bob
