I have found an old script (printout only) that I used to use to clone RH9.0 onto a USB disk !! #mount the new disk, something like mount /dev/sdb1 /mnt/zip umask 0 #Copy "nearly" all the top level directories #Avoid /proc, /dev, /tmp cp -rdpx /bin /mnt/zip cp -rdpx /etc /mnt/zip ... ... #Not sure whether with hal, udev and friends this is #still necessary (cd /dev;find . -print | cpio -pmd /mnt/zip/dev) mkdir /mnt/zip/proc mkdir /mnt/zip/tmp chmod 777 /mnt/zip/tmp #Edit /mnt/zip/etc/fstab as required #Edit /mnt/zip/boot/grub/grub.conf as required(This #assumes /boot and / are in the same partition !!)
