I was copying all of the gentoo system to a other disk (mounted it ro before) with rsync and burned the data to a DVD. I forgot to make the DVD bootable but it was possible to boot the DVD by using a existing kernel on the harddisk and giving him the option "root=/dev/hdc" (the DVD device). The system was booting and running stable. But it didn't liked a read-only /var and /tmp and /etc/mtab.
By making the DVD bootable and storing a kernel in the bootimage-part, changing the /etc/fstab to have ramdisks for /var and /tmp and you are able to boot the whole system from the DVD. Sorry for the long answer. I recommend finally this: create a big enough partition to store the gentoo installation then copy it with rsync (or similar tools) to this partition, using an emergency boot cd or mount the most as read-only before. you can burn the data from this partition without any risk in the case of an emergency you are able to boot your old installation from the partition (using grub for that, lilo is not flexible enough) best Martin -- [email protected] mailing list
