Re: [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.

Hi Y'all,
  I'm using the -J mkisofs option to put Joliet extensions in my ISOs, 
so that I get better long filename/path support.  However, when I do 
that, mkisofs spits out a warning that I am omitting Rock Ridge 
Extensions, and that it is "highly recommended" that I add them.

I've never had any problems reading CDs burned from ISOs where this 
warning was given.  But I also don't like warnings, if I can avoid them.

Only problem is, I can't figure out how to add Rock Ridge.  RR seems to 
be the default if -J *isn't* specified, but also appears to be turned 
off if -J *is* specified.  I tried --force-rr, but that didn't work (and 
more careful reading of the manpage sort of explained why)..  But even a 
pattern search through the manpage for "rock ridge" doesn't seem to tell 
me how to add Rock Ridge to a Joliet ISO.

So.  How do you do it?  (-:
Thanks!
