VACFS(4) VACFS(4)
NAME
vacfs - a Venti-based file system
SYNOPSIS
vacfs [ -dips ] [ -c cachesize ] [ -h host ] [ -m mtpt ] [
-S srvname ] vacfile
DESCRIPTION
Vacfs interprets the file system created by vac(1) so that
it can be mounted into a Plan 9 file hierarchy. The data
for the file system is stored on venti(8) with a root fin-
gerprint specified in vacfile. 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.
Options to vacfs are:
-c cachesize The number of file system blocks to cache in
memory. The default is 1000 blocks.
-d Print debugging information to standard error.
-h host The network address of the Venti server. The
default is taken from the environment variable
venti. If this variable does not exist, then
the default is the metaname $venti, which can
be configured via ndb(6).
-i Use file descriptors 0 and 1 as the 9P commu-
nication channel rather than create a pipe.
-m mtpt The location to mount the file system. The
default is /n/vac.
-p Disables permission checking.
-s Post the 9P channel in /srv/vacfs rather than
mounting it on mtpt.
-S srvname Post the 9P channel in /srv/srvname rather
than mounting it on mtpt.
