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 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.

­-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 communication 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.
