 The method is based on the capability of the syslinux family bootloaders (syslinux, isolinux, extlinux, pxelinux) to load multiple initramfs images during boot. If you are using Grub you could still use this method by chainloading from Grub to a syslinux family bootloader. It is also possible to pass multiple initramfs images to linux [[http://en.gentoo-wiki.com/wiki/Initramfs#Multiple_initramfs|from grub directly]], as well as from [[http://www.ipxe.org/cmd/imgfetch|iPXE]] / [[http://etherboot.org/wiki/commandline|gPXE]]. The method is based on the capability of the syslinux family bootloaders (syslinux, isolinux, extlinux, pxelinux) to load multiple initramfs images during boot.
