vacfs – a Venti-based file system


vacfs [ -dips ] [ -c cachesize ] [ -h host ] [ -m mtpt ] [ -S srvname ] vacfile


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 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:

-c cachesize

The number of file system blocks to cache in memory. The default is 1000 blocks.  


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).  


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 /n/vac.  


Disables permission checking.  


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.
