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.
