Hi All,
Fedora 34
bind-chroot-9.16.16-1.fc34.x86_64
I am trying to clean up my bind-chroot forward and reverse files.
The goal is to have bind-chroot do its thing by duplicating these two
files over into
/var/named/chroot/var/named/slaves/
with the identical inodes like it does with named.root and named.root.key:
# stat /etc/named.root.key /var/named/chroot/etc/named.root.key
...
File: /etc/named.root.key
Inode: 60033354
...
File: /var/named/chroot/etc/named.root.key
...
Inode: 60033354
In my /etc/named.conf, I have
zone "abc.local" {
type master;
# file "/var/named/chroot/var/named/slaves/abc.hosts";
file "slaves/abc.hosts";
allow-update { key DHCP_UPDATER; };
};
zone "255.168.192.in-addr.arpa" {
type master;
# file "/var/named/chroot/var/named/slaves/abc.hosts.rev";
file "slaves/abc.hosts.rev";
allow-update { key DHCP_UPDATER; };
};
After I stopped
# systemctl start named-chroot
I copied and moved the following:
Before:
# find /var/named/ -iname abc.hosts\*
/var/named/chroot/var/named/slaves/abc.hosts.000
/var/named/chroot/var/named/slaves/abc.hosts.rev.000
# cp /var/named/chroot/var/named/slaves/abc.hosts
/var/named/chroot/var/named/slaves/abc.hosts.000
# mv /var/named/chroot/var/named/slaves/abc.hosts .
# cp /var/named/chroot/var/named/slaves/abc.hosts.rev
/var/named/chroot/var/named/slaves/abc.hosts.rev.000
# mv /var/named/chroot/var/named/slaves/abc.hosts.rev .
# find /var/named/ -iname abc.hosts*
After:
# find /var/named/ -iname abc.hosts\*
/var/named/slaves/abc.hosts.rev
/var/named/slaves/abc.hosts
/var/named/chroot/var/named/slaves/abc.hosts.000
/var/named/chroot/var/named/slaves/abc.hosts.rev.000
But when I restarted named-chroot, my great plans got dashed:
# systemctl start named-chroot
...

named-chroot can't find abc.hosts or abc.hosts.rev in
/var/named/chroot/var/named/slaves
And in case they got copied to somewhere else I did another find:
# find /var/named/ -iname abc.hosts\*
/var/named/slaves/abc.hosts.rev
/var/named/slaves/abc.hosts
/var/named/chroot/var/named/slaves/abc.hosts.000
/var/named/chroot/var/named/slaves/abc.hosts.rev.000
No change.
What am I missing?
Many thanks,

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