Duplicando una maquina con rsync
rsync -v -r -p -o -g -D -t -S -l -H \ --exclude /mnt/ \ --exclude /proc/ \ --exclude /tmp/ \ --exclude /home/ / /mnt/fireball/
Boot from a CD-ROM and mount the target-disk. Fix fstab and lilo.conf. Create /mnt and /proc and set the right permissions (for this directories). Then run lilo and reboot. Next time you run rsync, add these option to the command-line:
--exclude /etc/fstab \ --exclude /etc/lilo.conf \ --delete
