Yes, you can point multiple zone { } definitions at the same file, but you
have to be careful what you put into the file: use only relative names,
e.g. just "foo", for names underneath the zone, and use "@" to refer to
the zone itself. Names which are constant for all zones, e.g. if you're
directing mail for all of these zones to a single set of mail servers,
should, as always, be fully-qualified and dot-terminated.

E.g.

@ soa ns1.constant.domain.  root.ns1.constant.domain. (
        (etc.)
    )
    ns ns1.constant.domain.
    ns ns2.constant.domain.
    mx 0 mail.constant.domain.
    a 1.2.3.4
www cname @
ftp a 2.3.4.5
pop a 3.4.5.6
(etc.)
