Hi!
I write here as the MAINTAINERS file has no entry about the isofs.
The question is : Is there any plan/way/idea to have read/write support
for isofs ?
I know of user space tools that can perform any operation (like
create/read/write/rename/delete file/directory) but that is nowhere
as convenient as a real filesystem.
Use case: Editing a iso9660 filesystem on a DVD+RW. With a r/w isofs most
changes would take a few seconds, while without, the entire 4.5 gigabytes
must be copied to HD, edited and then remastered back to the DVD medium.
(Why I don't use another FS ? Because I use the DVD to store music for
my car cd/dvd player and it understands only iso9660.)
(neither does it know vorbis. Or aac+ :-( )
Regards,
David Balažic

No. ISO-9660 is not meant to be randomly written, just like romfs,
cramfs and squashfs and .tar.gz/.tar.bz2 files. Userspace tools
recreate the whole ISO (or are very smart in reordering blocks). Use
UDF instead.

I find it hard to believe any device that can read a DVD doesn't support
UDF. That would be a very dumb design choice.
UDF was designed for read/write use. iso9660 was very much designed for
read only. It is much more complex to update an iso9660 filesystem
after it is created. It just wasn't meant for it.
