Excellent question, one I don't have a complete answer for since I've never tried it. Why not load the whole operating system and all the data a person would ever use in there as well? Knoppix has a boot option which allows you to copy all the iso files into RAM. Grab the DVD, boot it toram(if possible on DVD), install WoW into home; that should be about 20GB. When I look at this situation I wonder what is happening on the Front Side Bus and how much of the important data is getting down the channels ahead of non-important. DSL is a derivative of knoppix with the same boot option and when it is booted toram there is still lag due to 100% cpu; Moore's law if you will. How much of the cpu usage is user instructions or system duties like memory management. Filling the tables with pointers to dormant data would increase the Big "O" and place even more demand on an already taped out tech.

Looking at a Motherboard we see it is covered in circuits. For the machine to be operating at 100% efficiency, all the circuits should be pulsing with data simultaneously. The MPU should be at 100% as well as cache memory. One way of side stepping Moore's Law is multitasking the hardware better and increasing bandwidth. Offloading common operations onto hardcoded processors with a direct connection to main cpu and system bus, etc.. But I digress, the most important reason to do this is as a means of upgrading an old computer at low expense. I highly recommend trying to run DSL on an older cpu, it seems the world needed better software a lot more then faster processor speeds. Older machines can act as Firewall/Router/Gateways, web servers, tor servers, file servers, wireless monitors, etc.. Don't sell or throw away that xbox because it has many years left running the latest kernel code.

NAME
bootcdbackup - create a bootable offline backup of a unix system SYNOPSIS
bootcdbackup [-i] [-v] [-s] [-c <config directory>] [-url <url] [-nomount] [-2diskconf <file>] <dev> <name> <builddir> DESCRIPTION
bootcdbackup creates a offline backup from a installed system. You need a running bootcd to boot the system with. This CD/DVD is booted on the system and bootcdbackup creates a bootable CD/DVD with the bootcd kernel and the backup disk as tar-file. To restore or clone the system, boot the CD/DVD image and install it with bootcd2disk -c <name> on the system. bootcdbackup can try to discover the disk partition by searching for fstab on the given partition. A other way to backup the partition ta- ble is the program bootcdmk2diskconf which creates a configuration file on a running system. OPTIONS
-i The bootcdbackup runs in interactive mode and you can run each function manually. This option is useful for debugging. -v The option "-v" (verbose) adds messages on running. -s This option can be used to disable interactive questions and to try to ignore errors. -c <config directory> The configuration directory which includes the file "bootcdbackup.conf", default is "/etc/bootcd". -url <url> If bootcdbackup is slow on your system (because of a slow CD/DVD drive or the HP ILO virtual CD interface), you can use an image server to get the image from. bootcdbackup use the SWAP partition of your upcoming system as temporary space and copy the image from the configured image server to this partition and use it as image. The image server url is configured with this option. -nomount The target disk should not be mounted and no search for fstab is done. --cpio Normally as backup tool star will be used if selinux files have to be backed up and cpio will be used if not. With this option the usage of cpio can be forced. --star Normally as backup tool star will be used if selinux files have to be backed up and cpio will be used if not. With this option the usage of star can be forced. -2diskconf <file> The parameter configures a bootcd2disk.conf for the restore of the system done by bootcd2disk. The configuration file can be created with the command bootcdmk2diskconf. <dev> Configures the device where bootcdbackup finds the file "fstab" and discover the configuration for the restore. <name> The name of the backup (no blanks!) is used on the creation time and to restore the backup with bootcd2disk -c <name>. <builddir> Builddir is an directory on the backup system where bootcdbackup build the backup CD/DVD. Space for the CD/DVD image, for compression and the data is needed! All other configuration has to be done in the config files. FILES
