I've been updating my Linux OS for the past couple of years from Distros that come with monthly Linux Magazines. Linux Format, mainly. This past month TWO Linux magazines had the same Distro on their Cover DVD: SUSE 10.0. On the surface, it appreared they were both the same, but wait, One had OSS on the distribution.
The OSS version from Linux Format was not as Full as the Real SUSE 10.0 not OSS from Linux Magazine. This Not OSS version had more cutting edge programs from Novell than the OSS version. A half-hour upgrade installation time later, I was back in business running the latest from my favorite Linux OS.
