This probably a step in the wrong direction. In this way mount(8) should be aware about all types of filesystems and their flags/options/etc. May be fs (kernel part) can report these options as string to the given userland buffer ? It is not necessary to use existing statfs struct - now we have a very flexible VOP_GETEXTATTR() with corresponding syscall. > If some other people display intrest in this, and someone can suggest > a less ugly way of getting the definitions of <fs>_args into mount.h > (the only other way I can think of is to just move all of them from > <fs>/<fs>.h to mount.h permamently), I'll implement this stuff in the > other filesystems.
