I gave it a try with 7.2.1511 and that works fine as long as I have "ip=eth0:dhcp" in my PXE config. As soon as I expand it to "ip=eth0:dhcp ip=eno1:dhcp rd.neednet=1" (I do that to make sure kickstart works independently from the name of the network interface), kickstart enters into emergency mode w/o any error message after a lot of timeout warnings. However that's something we can work around. Thanks for the 7.2 hint. frank
