Thus, the first thing that has to be done is data collection. Always use lots of sub-directories and use data compression where possible. Excellent compression programs in combination with tar are gzip and bzip2 . Now that you have collected all your data, you may want to check whether it will fit on one CD or not. Next, all your data has to be formatted into the CD-ROM ISO9660 file format.
Little variations are possible.
To create the huge 650MB CD-image file, use the command mkisofs . Here is a list of some parameters you may use. You can combine most of these without any problems. Again, mind that doing it like this will only work for single-session CDs. It is advisable to use many sub-directories to make it easier to find stuff on your CDs a few years later.
