.SH DESCRIPTION
|
|
.I Vacfs
|
|
interprets the file system created by
|
|
.MR vac (1)
|
|
so that it can be mounted into a Plan 9 file hierarchy.
|
|
The data for the file system is stored on a Venti server
|
|
with a root fingerprint specified in
|
|
.IR vacfile .
|
|
.I Vacfs
|
|
is currently rather limited: access is read-only,
|
|
clients are not authenticated, and groups are assumed to
|
|
contain a single member with the same name.
|
|
These restrictions should eventually be removed.
