Since http://dracut.git.sourceforge.net/git/gitweb.cgi?p=dracut/dracut;a=commit;h=3df3a99759a9253113a88fb708c721c282fa7c3c, dracut uses the boot option rd_ZNET instead of rd_CCW to configure s390 network devices for use with a network root file system. This change is already in RHEL6 and should be reflected accordingly in the installation guide. rd_CCW is misleading since also non-network devices such as DASD use channel command words (ccw). rd_CCW was never used in an official release and it should never be used in the future. Actually, we always wanted this specific network config parameter to be called rd_ZNET and this change completes the consistency.
Please simply find & replace the string occurrences of rd_CCW with rd_ZNET. That's all. There are probably two occurrences in the chapter on configuring an installed Linux on System z instance, specifically the section on configuring a System z network device for network root file system.
