26 .SH DESCRIPTION
27 .I Vacfs
28 interprets the file system created by
29 .MR 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 a Venti server
32 with a root fingerprint specified in
33 .IR vacfile .
34 .I Vacfs
35 is currently rather limited: access is read-only,
36 clients are not authenticated, and groups are assumed to
37 contain a single member with the same name.
38 These restrictions should eventually be removed.
