Nope, it's ext2, and that's compiled directly into the kernel. > I think you could just drop the initrd and boot straight to usb; like > APPEND root=/dev/sda1 I thought about that, but it seems that USB devives are not always mounted at /dev/sda1. Somehow i even needed to mount /dev/sda to get the first(and only) partition on my USB stick. That's why i've written a script and would like to execute that and do the mount part myself :) > > I can't help more than that, never used syslinux or initrd.. > Though I did create a 2-floppy system for building LFS with the livecd, but > that's another story..
