[TriLUG] Rock Ridge Extensions

[Joel Ebel]

There's nothing wrong with having a rock ridge and joliet combined cd. 
I've seen the frequently.  Most of Red Hat's iso's are made this way. 
However, if you don't need linux style permissions and ownerships 
there's no need to do it.  All you need is -R for rock ridge and -J for 
Joliet.  They can coexist fine.
