The OS I am currently working on is FreeBSD. In addition, our file system 
has lots of additional attributes, like Hidden, System, RO, and Archive 
bits, NT-like ACLs, NT-like time stamps, and so forth, so a more generic 
approach to retrieving attributes would be more useful. However, I am also 
warming to some of the things that Reiser4 has in it as well.
