5 Acknowledgments

The history of Linux is a success story about countless developers all around the world
contributing to what originally started as a one-man show by Linus Torvalds. Thanks
to all of them for their tremendous efforts.

Especially we would like to thank all the people involved in the Linux for IBM System
z project at IBM and SUSE. Thanks to the (information) developers at SUSE and IBM,
the test team at SUSE, and all beta-testers and proofreaders at IBM. Thank you for
making SUSE Linux Enterprise Server for IBM System z possible.
