DHCP entries in /etc/config/dhcp will not automatically create A or PTR
records. Add an "option dns" directive which appends an entry to
/tmp/hosts/dhcp to facilitate forward and reverse DNS lookups. For
instance, this item:
config host
option ip '192.168.0.10'
option mac '00:13:57:9b:df:02'
option name 'winpc'
option dns '1'
will add a corresponding entry to /tmp/hosts/dhcp:
192.168.0.10 winpc.lan
This keeps the hostname/IP/MAC in a single place, for easy maintenance.
Related: ticket #13854 reports an regression involving missing PTR
records when using "config domain" to define static DNS entries for
individual hosts. However, per Simon Kelley[1], the --address feature
used by "config domain" was never intended to generate DNS A records for
hosts. It would probably be better for the reporter to apply this patch,
and then use "config host" sections instead of "config domain" sections.
