'managed-keys' is deprecated ??

[ToddAndMargo]

Hi All,

Fedora 34
bind 9.16

The Duck is failing me.

Placing
    include "/etc/named.root.key";
in my bind.conf, give me the following error:

# named-checkconf -l -t /var/named/chroot /etc/named.conf
/etc/named.root.key:1: option 'managed-keys' is deprecated

What do I use in its place?

Many thanks,
-T
