I did try fiddling with the offer cache timeout, but it doesn't seem to help
in this case. Is the DHCP server source going to be included in OpenSolaris? ;-)
I went searching for the Bug ID when logged in on sunsolve.sun.com, but it
didn't turn up. Oh well, makes this thread worthwhile - once it gets
indexed, at least non-Sun folk will quickly find some mention of the problem.
