Bad answer. ;-) It's for the ISO 9660 file system (as it writes), > not the .iso file format. It's two different things. The reason of saying that it's standard is that a file in `.iso format' is an exact image of an ISO standard filesystem. Whatever conventions are mentioned in the standard, they are the same in an `.iso format file'. If ISO 9660 says the root directory starts at byte XXX, there it starts in the image. If ISO says the integers will be encoded in both little-endian and big-endian formats, so they are in the image. > For example you > can store macintosh filesystem in .iso file and you can't mount by > mount_cd9660 of course but it still an .iso file. Right? If the image you stored is indeed an image of an ISO filesystem, I can. man vnconfig (4.x) or man mdconfig (5.x). If not --- well, I can store a picture of a nude <ethnic> in JPG format and name it to have an .iso extension. Surely we are talking about formats, not extensions. I don't mean the .iso extension is standard. You can make it `.yabadabadoo' if you prefer. I don't mean that an `.iso format file' can describe absolutely anything (audio, etc.). But it does its job. A waek analogy, but if I measure my weight with the device at hand and tell you the number in kilograms, you won't object saying that I didn't use the international platinum-iridium kilogram for my measurements? An =2Eiso image is an `instance' of an ISO filesystem, just as my weightometer:) is an `instance' of that kilogram. --=20 DoubleF Excessive login or logout messages are a sure sign of senility. --nFreZHaLTZJo0R7j Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (FreeBSD) iD8DBQFA4VoEwo7hT/9lVdwRAvjeAJsFerTVnQKt1l9Z7jfIZORVceysywCbBPtK RLMHfqpTnJXPlmU4Lc0ai84= =T8Nt -----END PGP SIGNATURE----- --nFreZHaLTZJo0R7j--
