I could, and then at some point in the future someone would complain,
(legitimately) that it's really very confusing that a configuration file
which works fine when dnsmasq is started for the first time fails if
it's re-read. Then I need to solve the problem that on a re-start there
can be no fatal errors - the daemon is running and has to continue
running, so the effect of doing a re-load is that facilities that were
working, mysteriously, partially fail. As a matter of design, it's
problematic.

Can anybody answer this?

Cheers,
