Introduction

Being able to make one's own version of SystemRescueCd was a frequently requested feature. It's now possible to make your own version of SystemRescueCd.

This means you will be able to add files to the sysrcd.dat compressed image file, which will be the filesystem of SystemRescueCd. For example, you can add script files that make a full backup of a server, or a binary program that you need. It's also possible to add data files, in order to have everything on the CDRom (data and system files which allow you to restore data). For now, it's not possible to change the kernel. If you need a kernel option that is disabled, please contact us.

The goal is to produce a new ISO image file, with an updated sysrcd.dat. In order to be able to make your own version of SystemRescueCd, you will need a recent official version of this CDRom, and a partition with read-write access from within linux, with at least 500 MB. If you make a very large version of the CDRom, you may need a lot more space.

Be aware that this operation requires a large amount of memory (both RAM and space on the hard disk). If you don't have 128 MB of RAM, and at least 300 MB free on your hard disk, it will fail. You can create a swap partition in order to avoid problems with the cloop step in the script.
