Please note that I'm not blaming [nor in position to blame] anybody for
choices they make. I merely *encoraged* public to open up, as it felt
there is a need for that. My comment was *not* based solely on that
particular remark, so don't take it personally.

Modesty is of course valuable quality, but keep in mind that it's a
*discussion* forum. Statement or proposed solution doesn't have to be
100% correct or perfectly suitable for some particular situation. That's
why we *discuss* it, don't we?

Once again. Keep in mind that Linux isofs implementation is deficient in
such way which effectively limits maximum file size to 2G-1 byte. I mean
even if kernel itself supports large files and all application programs
are explicitly compiled with large file support, you still get into
trouble [as long as we're talking about ISO9660 that is]. I assumed that
Ashish was referring to this limitation, as it was discussed serveral
times on this list. I might be wrong in my assumption (but that's OK as
already established:-). Cheers. A.
