Right. The initrd file is just a file in /boot. Copy it over too and set up grub like: kernel /boot/vmlinuz-2.6.20-16-generic ... initrd /boot/initrd.img-2.6.20-16-generic The problem there probably is that they don't have the filesystem drivers built into the kernel. Use the Centos /boot/grub/menu.lst as a guide. -- Bruce -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
