Along with some excellent help for Ed over on the
Fedora mailing list, I did get it figured out.
I got my ass handed to me on step 2.

Here are my notes:

bind-chroot: how to start over clean:


On 6/27/21 5:34 PM, Ed Greshko wrote (with additions from T):

0) backup your zone tables (3+), named.config,
    named.root.key, named.local files

1) stop named-chroot,
       # systemctl stop    named-chroot.service
    Verify it is dead:
       # systemctl status  named-chroot.service

2) start the named server
       # systemctl start   named.service

    make sure it doesn't produced errors.  Fix any you do find

    To check errors:
        # systemctl status    named.service

3) If that check ok, then stop named.
       # systemctl stop    named.service

4) Then do

    Remove:
       # rpm -e --nodeps bind-chroot
       # rm -rf  /var/named/chroot

    Reinstall:
       # dnf install bind-chroot
       # systemctl enable  named-chroot.service


5) Then, without moving any files or doing anything, start named-chroot
       # systemctl start   named-chroot.service


6) double check your mount --bind's

    # stat /etc/named.root.key | grep    Inode | awk '{print $3 " " $4}'
