No problem, it's a good question.

I'm not the correct person to give an unbiased answer on this, but I'll
shove my oar in anyway. I'm very happy to hear other people's opinions
on this, good or bad.
Dnsmasq 2.x, which is the version which added DHCP, is now 11 months and
18 releases old: Adding the DHCP support was my "escape from Christmas"
project last year. Of those 18 releases, about 14 have been almost
exclusively feature upgrades or fixed specific bugs with limited impact.
One was to fix a bug caused by the non-POSIX compliance in the Linux
kernel which was never seen in anger and also affected glibc, syslogd
and inetd, at least. Three were to supercede flawed releases which
crashed, in each case the crash bug was found and fixed in a few weeks.
In other words, if you follow the bleeding edge,there's a chance you
might get burned, but otherwise the code is stable and usable.
I've been thinking for some time that I should make stable and
development branches, but each time I've convinced myself that dnsmasq
2.x is now finished, so I don't need a development branch. I think that
this is probably a delusion.
Aside from the risk of Simon-induced problems in a latest release, I
don't think there's much question that the code is ready for the sort of
use you are proposing - the basic design has had much testing over
several years, and the current code is in widespread enough use that all
the common problems have been found.
What do others think?
