I'm trying to implement a write method and I partially succeeded by making a #write and an #open method: Now I can echo foo >> mnt/bar to that FS. :)

I still can't do cp foo.txt mnt/bar.txt (giving me cp: cannot create regular file 'mnt/bar.txt': Function not implemented) or echo foo > mnt/bar (giving me function not implemented: mnt/bar).

I guess I have to implement #truncate for the latter … but how?
