This is the function I need ! but ... I have test it, and it don't work, 
I put the min-secs in my range but the DHCP send an offer without delay 
(min-secs delay).
Have you got an idea  why the delay don't work ? ( I have tested out of 
the range (at the start of dhcpd.conf) but it's the same result...)
