imgargs (ipappend 2 for red hat kickstart)

kernel vmlinuz
ipappend 2
append initrd=initrd.img ks=http://server-ip/kickstart.file.ks network ksdevice=boofit

Is there anyway to make this work in iPXE?

I have tried to just insert ipappend 2 in imgargs, but that just wont work. I can skip it, and use ksdevice=eth0, but what about our users that have multiple nics in their machines?

According to http://www.syslinux.org/wiki/index.php/SYSLINUX, the "IPAPPEND 2" will cause PXELINUX to add the text "BOOTIF=<hardware-address-of-boot-interface>" to the kernel command line. You can replicate this behaviour in iPXE by expanding the ${netX/mac} variable. For example:

Code:

#!ipxe
kernel vmlinuz ks=http://server-ip/kickstart.file.ks network ksdevice=bootif BOOTIF=${netX/mac}
initrd initrd.img
boot
