Hi Jacco.
May I suggest adding this attached little DHCP helper script to RSEL6
(and maybe RSEL7 if dhclient is the same).
This script print the DHCP address while booting.
Very useful when installing a new Raspberry with no attached keyboard :)
I made it myself - dunno if a similar script exists in any distribution ?
BR,
Bjarne
