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