So if I use my space in /usr/tmp, would I use the cmd given by
cpghost:
% mkisoft -R -J -o cdr.iso /usr/tmp/cdr/ ? If this wouldn't
% create the RockRidge extension, what then?

Tried that; get lost after the first few clicks... Got to be
'too-too simple' :)

---just between you and me, Polyt, i've got to watch my fingers;
i might type "floppy dick" and that would get lots of snickers... .

Exact "where do I click" instructions, please. Alao, if I'm
brave enough to use GUI, can I use ~/devel, ~/Music, and, say
~/texts? ---I have learned to mouse-around and select my
favorite mp3 and ogg-vorbis tunes, but that's just 80 minutes of
music. No mount, no umount.

Something like that happened a couple months ago.... (*sigh*)

OK, then what about the mount, umount commands?
% mount /dev/cd0 /mnt
// cd to /dev/dv0, read, listen, whatever. Then::
% umount /dev/cd0
?? Would this work with our FBSD filesystem and-or RockRidge?
