This patch changes how parameters are passed to dnsmasq. Instead of
being on the command line, the parameters are put into a file (one
parameter per line) and the command line parameter --conf-file=
to specify the location of the file. This file is located in
the same directory as the leases file.
This also adds the dnsmasq parameter interface=<net-name>
The change of putting the parameters into a configuration file
allows them to be examined and more easily understood than
examining the command lines displayed by "ps ax". This is
especially true when a number of networks have been started.
I suspect that when the use of dnsmasq was originally done,
the command line was simple but has gotten more complicated
over time and will likely become even more complicated in the
future.
I believe that if use of dnsmasq was done today with
the current requirements for dnsmasq, a configuration file
would have been used. Many (most?) daemons use configuration
files as oppose to command line parameters.
One potential addition to dnsmasq parameters is to specify
the reverse-lookup queries which are not to be passed on up
the chain. For IPv4, such queries are rather simple and
take the form:
<ipv4_address>.in-addr.arpa
but ipv6 queries involve a lot longer specification. The
IPv6 query will be of the form:
<ipv6_address>.ip6.arpa
where the above query expands to a 44 character string which is
specified by --local=/<ipv6_address>.ip6.arpa/ which is
certainly a lot of clutter to add to the command line.
