One problem is that you never really know which device your USB stick is at, a solution is to upgrade busybox in the initrd to one with CONFIG_FEATURE_MOUNT_LABEL=y and set a label on the USB stick. Then let the linuxrc script mount root by label. This is what I have done in my setup, but with an initramfs and the EeePC kernel from www.array.org/ubuntu -- /Jonatan [ http://kymatica.com ] _______________________________________________ gobolinux-devel mailing list gobolinux-devel@lists.gobolinux.org http://lists.gobolinux.org/mailman/listinfo/gobolinux-devel
