That's good.

Hmmm. CNAMEs in reverse zones are very common. RFC2317 is widely
implemented. [9.242.6.62.in-addr.arpa - the reverse entry for my
computer - is a CNAME.] I wonder how DDNS implementations cope with
that? ie "If the reverse entry is a CNAME, follow it and replace or
update whatever that CNAME points at."

BTW, there's no rule that says only PTR records go in reverse zones.
