Advantage to namei is "it's just another user of the filesystem" so it
works pretty much with any underlying filesystem, including filesystems
with "advanced" features like journalling or logging.

Disadvantage to namei is you have the overhead of going through the
filesystem. 

There was a presentation at Usenix about a "library for using a raw disk
partition" I think called Hummingbird but it was something whoever (I
think Bell Labs) wanted you to license, making it not interesting for this
project. But it might be interesting to be a user of raw disk.
