Ok, I used;
samba-tool dns add 127.0.0.1 example.com debian CNAME centos.example.com
a query now returns;
Name=centos, Records=1, Children=0
A: 192.168.1.11 (flags=f0, serial=2, ttl=900)
Name=debian, Records=1, Children=0
CNAME: centos.example.com. (flags=f0, serial=23, ttl=900)
and 'dig @192.168.1.254 debian.example.com. IN CNAME' returns;
[...]
;; QUESTION SECTION:
;debian.example.com. IN CNAME
;; ANSWER SECTION:
debian.example.com. 900 IN CNAME centos.example.com.
[...]
However, neither 'debian' nor 'debian.example.com' resolve to an IP, yet
the output from dig implies the entry is correct? Of course, 'centos'
does resolve.
