Replying to [comment:4 axeld]:
> Why can the second file system open the image file read/write in the
first place?
Apparently because `dosfs_open()` [http://dev.haiku-
os.org/browser/haiku/trunk/src/add-
ons/kernel/file_systems/fat/file.c?rev=33670#L290 does things
incorrectly].
> This is what BFS checks for, and it will fall back to read-only if it
couldn't open it read/write.
Ah, indeed, I first missed that. If every file system with write support
did that (FAT doesn't for instance), that would work well enough.
