I've been banging my head against this problem for the last couple of days - until I found this BZ ... For what it's worth, I've managed to work round the problem by using an Anaconda updates image containing just the file /etc/dhcp/dhclient.conf - which contains the line: send vendor-class-identifier "myclass"; Verified on RHEL-7.3-20160901.1 with anaconda-21.48.22.86-1. dhcpclass from kernel cmdline is used in installer. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory, and where to find the updated files, follow the link below.

Description of problem: I wish to install RHEL, via kickstart, using DHCP. To do this in my environment I need a custom dhcp vendor identifier. There are options, "dhcpclass", to do this but it doesn't reach the highest level of anaconda properly. Process from my perspective: Server starts. PXEClient DHCPs a public ip in a build range by matching on vendor identifier. It uses the configuration file: ``` DEFAULT linux LABEL linux KERNEL boot/Fedora-23-x86_64-vmlinuz APPEND initrd=boot/Fedora-23-x86_64-initrd.img ks=http://build00.internal.ntoggle.com:80/unattended/provision ks.device=bootif network ks.sendmac inst.dhcpclass=foreman IPAPPEND 2 ``` This then starts (dracut?). Dracut does a DHCP request with the foreman dhcpclass correctly, and gets the same lease. At this point the automated install is started and we proceed until we reach: network --onboot=no --bootproto dhcp --hostname node00.internal.ntoggle.com --device=fc:aa:14:ae:f8:d2 --dhcpclass=foreman This then initiates another DHCP request with -no vendor identifier- as verified with Wireshark. It gets DHCPNAKed and fails to install at this point. From the DHCPd perspective: DHCPDISCOVER from fc:aa:14:ae:f8:d2 via enp2s0f0 DHCPOFFER on 66.150.120.242 to fc:aa:14:ae:f8:d2 via enp2s0f0 DHCPREQUEST for 66.150.120.242 (66.150.120.241) from fc:aa:14:ae:f8:d2 via enp2s0f0 DHCPACK on 66.150.120.242 to fc:aa:14:ae:f8:d2 via enp2s0f0 reuse_lease: lease age 22 (secs) under 25% threshold, reply with unaltered, existing lease DHCPDISCOVER from fc:aa:14:ae:f8:d2 via enp2s0f0 DHCPOFFER on 66.150.120.242 to fc:aa:14:ae:f8:d2 via enp2s0f0 reuse_lease: lease age 22 (secs) under 25% threshold, reply with unaltered, existing lease DHCPREQUEST for 66.150.120.242 (66.150.120.241) from fc:aa:14:ae:f8:d2 via enp2s0f0 DHCPACK on 66.150.120.242 to fc:aa:14:ae:f8:d2 via enp2s0f0 DHCPREQUEST for 66.150.120.242 from fc:aa:14:ae:f8:d2 via enp2s0f0: lease 66.150.120.242 unavailable. DHCPNAK on 66.150.120.242 to fc:aa:14:ae:f8:d2 via enp2s0f0 Version-Release number of selected component (if applicable): I have tested this against RHEL7.2 and Fedora 23. How reproducible: Well, every time? :) Steps to Reproduce: 1. Set inst.dhcpclass=something in a pxeboot 2. Set --dhcpclass=something in a kickstart 3. Watch it fail to make it to dhcpd. Actual results: A failed lease attempt. Expected results: The lease is picked back up. Additional info:
