VACFS(4)                                                 VACFS(4)

     NAME
          vacfs - a Venti-based file system

     SYNOPSIS
          vacfs [ -dip ] [ -h host ] [ -m mtpt ] [ -s srvname ] [ -M
          mem ] 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 a Venti server with a root
          fingerprint 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:

          -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.

          -i   Use file descriptors 0 and 1 as the 9P communication
               channel rather than create a pipe.

          -m mtpt
               The location to mount the file system. The default is
               not to mount.

          -p   Disables permission checking.

          -s   The name of the 9P service to post.  The default is
               vacfs.name, where name is vacfile without any directory
               name or `.vac' extension.

          -M mem
               The amount of memory, in bytes, allocated to the block
               cache. The default is 16M.
