.SH DESCRIPTION
27 
.I Vacfs
28 
interprets the file system created by
29 
.IR vac (1)
30 
so that it can be mounted into a Plan 9 file hierarchy.
31 
The data for the file system is stored on
32 
.IR venti (8)
33 
with a root fingerprint specified in
34 
.IR vacfile .
35 
.I Vacfs
36 
is currently rather limited: access is read-only,
37 
clients are not authenticated, and groups are assumed to
38 
contain a single member with the same name.
39 
These restrictions should eventually be removed.
