Scientific Linux Live CD 4.2 has been released for both i386 and x86_64 Many thanks go to Urs Beyerle and PSI for creating and documenting Scientific Linux Live CD 4.2. The Scientific Linux Live CD/DVD is a bootable CD/DVD that runs Linux directly from CD/DVD without installing (like Knoppix and many others). It is based on Scientific Linux 4 (SL4). It uses Unification File System (unionfs), allowing read-only filesystem to behave as a writable one and squashfs providing on-the-fly decompression that allows to store 2GB software on a normal CD-ROM. The Live CD/DVD was build using modified scripts from www.linux-live.org. It's now possible to save your session data and some configurations (keyboard, X11 configuration) to an USB stick (or to local hard disk): Just run save-localdata. For more documentation, you can go to https://www.scientificlinux.org/documentation/misc/livecd which currently is only a pointer to http://linux.web.psi.ch/livecd/ Urs has created both a 32 bit, and 64 bit release. He has also created a small version (fit's on business card size cd's), normal CD version, and a full blown DVD version.
