I usually use cp -ax or cp -avx if I want it echoed to the screen -- makes the process much slower though. Clearly, you don't need to copy /proc and /sys as they are regenerated each time you boot; you could just create the directories. There are also directories like /mnt and /home where you may want to review the contents first before you copy. If you are going to copy /boot and you want to boot from the copy make sure that the information in /boot/grub/menu.lst is still relevant to the new installation.
These all sound like good ideas to me. At this point you have a really simple system. What you really need to do is: copy: /bin /lib /usr /etc /boot /var to some sort of medium. To restore: just create a new filesystem on the partition, and copy the correct trees back. tar cvzf back_up.tgz /bin /lib /usr /etc /boot /var <anything else you need> Or cp -a, or dd, or whateva. ---Dan -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
