Okay, bare in mind the things mentioned elsewhere in the thread about
trying another sub-directory inside var/named for your dynamic records.
But what you've got now is probably important. The "defaults" sometimes
end up being different on different boxes. Perhaps due to whether users
just install BIND itself, or the local caching package?

As I've commented on below, I found allowing updates by IP address
hasn't worked for some time. I don't know if it works again in FC5.

Not sure if the "timed out" error is the same thing, or related. I've
gone through the same myself, but resolved it too long ago. Not sure if
the denials are file writing denials, or configuration of name server
allowances.
If the chrooted /var/named... (/var/named/chroot/var/named...) it's
trying to access now doesn't have the right permissions, it won't be
able to write those files. What are the current permissions?

Hmm, never seen the listen-on and allow-query statements refer to the
ACL before. Not sure if it's allowed, but my man file says it's port
and IP data inside listen-on. It does say that the allow-query is an
address match element, though.

I found that using addresses in the allow-update statement hadn't worked
for me since about Red Hat 8.0 Linux. I had to use an ACL name in
there, and that's all I've used. Seeing as you've set up one, acl
"bac-net", it seems rather redundant to then not use it and go about
manually specifying the addresses in all the places you could have just
put "bac-net", if you're also including addresses.
Not that it should make any difference, you can omit that full file
path. You've set it, above, with the directory statement.
For subdirectories, you can just prepend the subdirectory name.
i.e. slaves/example.com.zone
Mine would have been done just as:
zone "bac.org.au" {
type master;
file "bac.org.au.hosts";
allow-update { key rndckey;};
};

Are you using the same /etc/rndc.key between DNS and DHCP servers?
It'll need to be. That can be a /gotcha/ in chrooted servers.

Not sure if the above two statements (authoritative & ddns-updates on)
had to be done outside of the subnet clauses.

Fixed addresses won't get updated in the DNS records, you'd have to set
them in them manually.
