Sorry, not finished, do we have a hexdump utility function somewhere in akaros?
But with this we get stuff like this:
ramfs 2:<-Twalk tag 1d fid 16 newfid 19 nwname 0
ramfs 2:->Rwalk tag 1d nwqid 0d
ramfs 2:<-Tstat tag 1d fid 19d
ramfs 2:->Rstat tag 1d  stat '.' 'eve' 'eve' 'eve' q (0000000000000000x 70368744177664d d) m 2147484157o at 140183437574144 mt 140183437574144 l 0 t 0 d 0
ramfs 2:<-Tclunk tag 1d fid 19d
ramfs 2:->Rclunk tag 1d
ramfs 2:<-Twalk tag 1d fid 16 newfid 19 nwname 1 0:ifconfig
ramfs 2:->Rerror tag 1d ename file does not exist

Which is pretty nice. Now why the kernel is fouling up the create I don't know. The
walk fails, and it does not then say 'oh, let's create'. Barret? Kevin? anyone?
