Sure. But beware it's just a quick hack.

Then symlinks are working. Now you need to fix the uid/gid
problem and handle devices, named pipes and sockets in 9pserve.
Also, you should apply this patch:
http://codereview.appspot.com/download/issue5500097_1.diff
It fixes two problems:
- fix segfault when the first file is DMSYMLINK or DMDEVICE,
- set the buffer to zero before calling readlink.
Symlinks will not work without this patch.
