Here's the summary on this topic. My question is included at the
end of this message for those that didn't suffer enough by reading
CC:
it the first time. ;-)

(Sorry Brian, but you can't really expect not to get a little heat
for not filtering mailing list posts from your vacation program ;-)

Basically he said to edit the source and defeat the check for multiple
interfaces. While this was nice of him to offer, I already knew of a
way to get dhcpd to run (as mentioned in posting). What I wanted to
know was whether I was setting myself up for problems with dhcp by
hacking around the interface check (whether by downing the virtual
interfaces before starting dhcpd or by frobbing the source I think it
makes no difference). But thanks anyway Stan!

I wonder whether you are better off using suns dhcp which is explicity bound
to an interface.
Maybe. I had not heard of any DHCP server from Sun. (But I bet it ain't
free. ;-)

yes and www.isc.org
The REAL SUMMARY:
=====================
I went ahead and did it anyway and it has been working fine for 3 days
now (knock on wood).
I just wrote an S (and K) script in rc2.d that starts dhcpd before I
ifconfig the virtual interfaces and wrote a start|stop script for
init.d/ that downs the virtual interfaces when starting dhcpd and then
brings them up again when dhcpd has started succesfully.
Thanks to all who took the time to respond.
Cheers,
Andy
