I ran into two documentation errors: * The Red Hat Welcome page says Red Hat Linux 6.2 (file:/usr/share/doc/HTML/index.html) * In the Red Hat Linux Reference Guide, I'm not sure but I believe the option to the url command should be --url not --ulr. This is in the following file on the Docs CD: RH-DOCS/rhl-rg-en-7.0/s1-kickstart2-commands.html. I haven't tried it so I don't know for sure. It just looked like a typo and I can't find other references to it.
this has been fixed.
