I installed the following as the default-empty zone file for FreeBSD
back in 2007, and it has withstood numerous versions of BIND in the process:

$TTL 3h
@ SOA @ nobody.localhost. 42 1d 12h 1w 3h
        ; Serial, Refresh, Retry, Expire, Neg. cache TTL

@       NS      @

; Silence a BIND warning
@       A       127.0.0.1
