   Make sure you do not have two `named.root.key` kicking around.  One in
      /etc/named.root.key
   and one in
      /var/named/chroot/etc/named.root.key

I think you may be missing some key points as to how named-chroot works.

If you look at the named-chroot.service file you'd see.....

Requires=named-chroot-setup.service
Before=nss-lookup.target
After=named-chroot-setup.service

This means that named-chroot-setup.service runs prior to ExecStart in 
named-chroot.service

named-chroot-setup.service performs a series of bind-mounts (not be confused 
with bind/named)
You can see the mounts after starting named-chroot.

Thus you'd have.....

[root@f33g ~]# systemctl stop named-chroot
[root@f33g ~]# ll /var/named/chroot/etc/named.root.key /etc/named.root.key
ls: cannot access '/var/named/chroot/etc/named.root.key': No such file or 
directory
-rw-r--r--. 1 root named 686 Jun  3 22:47 /etc/named.root.key

[root@f33g ~]# systemctl start named-chroot
[root@f33g ~]# ll /var/named/chroot/etc/named.root.key /etc/named.root.key
-rw-r--r--. 1 root named 686 Jun  3 22:47 /etc/named.root.key
-rw-r--r--. 1 root named 686 Jun  3 22:47 /var/named/chroot/etc/named.root.key

To repeat what I've said in another thread.  I've upgraded 2 F33 VMs.  One 
running named.service
the other named-chroot.service.  Both upgraded without any problems you noted.
