almost...
[liveuser@localhost-live ~]$ sudo -i

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

    #1) Respect the privacy of others.
    #2) Think before you type.
    #3) With great power comes great responsibility.

[root@localhost-live ~]# mount /dev/sda6 /mnt
[root@localhost-live ~]# chroot /mnt
Error, do this: mount -t proc proc /proc
/usr/bin/basename: missing operand
Try '/usr/bin/basename --help' for more information.
bash.1[/]: mount -t proc proc /proc
bash.2[/]: less /var/log/dnf.log
bash.3[/]:

So now I can do "rooty" things in the workstation hard drive when using Fedora live.  I might need this soon....

A few times while trying to use Fedora live, the workstation froze while in Firefox. A few times, Fedora live did not shut down properly; and the cooling fan surged; and I had to do a hard manual shutdown. Twice, very early in boot-up, before the grub menu appeared, a warning about the cpu being hot appeared. Thursday, I had to go into windows-7 briefly to see if my board was bios or uefi; it froze during shutdown.

Both Samuel and Tim have made suggestions and asked questions that I want to follow up on.  But with hints of hardware trouble, I need to turn my attention to the hardware.  I'll open a new thread on that.

The questions I asked when starting this thread are answered.  I thank those who tried to help for their time and effort.  I've marked this thread "SOLVED".

Bill.
