Yes, "/usr/afs/bin" is a magic string.  Particularly, it is
AFSDIR_CANONICAL_SERVER_BIN_DIRPATH.  Any time this appears at the start of 
a path in a bosserver RPC, the server replaces it with 
AFSDIR_SERVER_BIN_DIRPATH.  It also does a number of other 
canonicalizations (/usr/afs/etc, /usr/afs/local, /usr/afs/logs), path 
transformation and so on.  In addition, a number of things which are 
nominally "paths" can actually be given as relative filenames.  So you can 
actually just say

# bos create foobar fs fs fileserver volserver salvager

and get reasonable results.

However, the transformation happens as an RPC is processed; the paths you 
give are not stored in canonical form.  So if AFSDIR_SERVER_BIN_DIRPATH 
changes (i.e. if you compile with a different value), the bosserver will 
not magically adjust its configuration.
