I'm getting in to burning CDs with linux now, and have a question about ISO. I notice that my CDROM was mounting as ISO9660 in /etc/fstab and any CD I popped into the drive would have short filenames. When I changed the file system to auto in fstab, the LFNs appeared. So obviously ISO doesn't support long file names directly.

Now, I read up (a tad bit) on the ISO file system and noticed there's something called RockRidge extensions that will add support for long file names. How compatible is this with other OSs? I mean, will a CD I burn in linux this way work in windows?
Usually when I burn a CD in windows the file system I use is Joilet..is there any real difference? Could I use Joilet when burning in linux? Lastly, is there any limitations to ISO that I will notice (ie. max filename length)..

The original ISO9660 spec only allows filenames in the 8.3 format, with capital letters, numbers, and the underscore being the only legal characters. Directory nesting is limited to 8 levels. The Rockridge extensions allow long filenames, the use of Unicode characters, and deeper directory nesting. Micro$oft created the Joliet extensions to give Win9x/NT boxen the same
capabilities Rockridge gives to other systems.
As far as interoperability and compatibility,check out the Filesystems HOWTO (http://www.linuxdoc.org/HOWTO/Filesystems-HOWTO.html).

I also found this page at a small little college down the street from me ;) : Joliet.html (http://bmrc.berkeley.edu/people/chaffee/joliet.html)
