Users of the genkernel tool have indeed made such an initrd file, perhaps without their knowledge.To use such an initrd file, you need to specify /dev/ram0 as the root file system and the real root file system with the realroot= parameter1. It is also adviseable to inform

How do I use a custom kernel?

Copy it into config/chrootlocal-packages and set LHLINUXPACKAGES=""Dont forget to compile your kernel with an union filesystem unionfs or aufs, squashfs modules, and initrd support.> I.g. placing the files in /boot as vmlinuz-version and initrd.img-version etc.I personally wouldnt go that way which is too much of a hassle, and just use make-kpkg to produce custom kernel deb packages
