Maybe I tested with an old version, but I was not able to load a file
with relative path without it being a cpio in UEFI mode
What worked for me, from an http server I chain load a ipxe script
with something like
~~~~
kernel ../kernel/vmlinuz initrd=initrd.img initrd=myks.cfg.cpio
inst.ks=file:/myks.cfg ...
initrd ../kernel/initrd.img
initrd ../ks/myks.cfg.cpio
boot
