Just over two weeks after the official release of Scientific Linux 5.6, the Scientific Linux (SL) developers have announced the arrival of the LiveCD and LiveDVD variants of version 5.6 of their Red Hat Enterprise Linux (RHEL) clone. The LiveCD/DVD versions allow users to run the distribution directly from a CD or DVD drive without having to install it. Alternatively, it can also be installed to the local hard disk or users can run the LiveCD image from a USB flash drive.
