       gdnsd.djbdns - gdnsd support for the djbdns tinydns zone data format




       This zone data backend implements the tinydns format described in

       As of this writing, djbdns file format support is considered EXPERIMENTAL.  Feel free to
       submit issues and/or pull requests to make the implementation and documentation more
       correct and complete!  There are probably many legal djbdns zone datasets that do not load
       correctly (or at all) yet.  However, there are users loading data from this in production.

       The djbdns zone data backend loads all files found within the djbdns subdirectory of the
       daemon config directory, default /etc/gdnsd/djbdns/.  Each file can contain multiple zones
       (identified by "Z" records).

       At this time, unlike the RFC1035 zone data backend, the djbdns backend does not support
       automatic reloading of updates based on filesystem notification.  It only explicitly
       reloads any changed data on "SIGUSR1" / "gdnsd reload-zones".


       The following record types are implemented in the parser:

       Z - SOA
           The "Z" type denotes the existence of a zone and defines its SOA-record.  All records
           within a file must be contained within a zone defined by a "Z" entry.

       & - NS (+ A)

       . - NS + SOA (+ A)
           The "." type is meant to create an SOA along with the zone's NS records.  At this
           time, gdnsd doesn't support this record for defining the SOA or a zone's existence,
           and treats it just like "&" above.

       @ - MX (+ A)

       + - A
           If the 5th field is "~~", this can be used to create "DYNA" records as well, with the
           "plugin!resource" part in the 2nd field.

       = - A + PTR
           The autogeneration of PTR records for "=" is not implemented yet, so this is treated
           identically to "+" above.

       C - CNAME
           If the 5th field is "~~", this can be used to create "DYNC" records as well, with the
           "plugin!resource" part in the 2nd field.

       \ - TXT

       S - SRV

       N - NAPTR

       3 - AAAA
           Not yet implemented.

       6 - AAAA + PTR
           Not yet implemented.

       ^ - PTR
           Not yet implemented.

       : - Raw
           Not yet implemented.
