.IX Title "sfscd_config 5"
.TH sfscd_config 5 "SFS 0.7.2" "2002-12-20" "SFS 0.7.2"
.UC
.SH "NAME"
sfscd_config \- meta-client configuration
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \fIsfscd_config\fR is really part of the \s-1SFS\s0 protocol
specification.  If you change it, you will no longer be executing the
\&\s-1SFS\s0 protocol.  Nonetheless, you need to do this to innovate, and \s-1SFS\s0 was
designed to make implementing new kinds of file systems easy.
.PP
\&\fIsfscd_config\fR takes the following directives:
.Ip "Extension \fIstring\fR" 4
.IX Item "Extension string"
Specifies that \fBsfscd\fR should send \fIstring\fR to all servers
to advertise that it runs an extension of the protocol.  Most servers
will ignore \fIstring\fR, but those that support the extension can
pass off the connection to a new ``extended'' server daemon.  You can
specify multiple \fBExtension\fR directives.
.Ip "Protocol \fIname\fR \fIdaemon\fR [\fIarg\fR ...]" 4
.IX Item "Protocol name daemon [arg ...]"
Specifies that pathnames of the form
\&\fI/sfs/\fR\fIname\fR\fI:\fR\fIanything\fR should be handled by the
client daemon \fIdaemon\fR.  \fIname\fR may not contain any
non-alphanumeric characters.  The \fBProtocol\fR directive is useful
for implementing file systems that are not mounted on self-certifying
file systems.
.Ip "Release {* | \fIsfs-version\fR}" 4
.IX Item "Release {* | sfs-version}"
Begins a section of the file that applies to servers running \s-1SFS\s0 release
\&\fIsfs-version\fR or older.  \fB*\fR signifies arbitrarily large \s-1SFS\s0
release numbers.  The \fBRelease\fR directive does not do anything on
its own, but applies to all subsequent \fBProgram\fR directives until
the next \fBRelease\fR directive.
.Ip "Libdir \fIpath\fR" 4
.IX Item "Libdir path"
Specifies where \s-1SFS\s0 should look for daemon programs when their
pathnames do not begin with \fI/\fR.  The default is
\&\fI/usr/local/lib/sfs-0.7.2\fR.  The \fBLibdir\fR
directive does not do anything on its own, but applies to all
subsequent \fBProgram\fR directives until the next \fBLibdir\fR or
\&\fBRelease\fR directive.
.Ip "Program \fIprog\fR.\fIvers\fR \fIdaemon\fR [\fIarg\fR ...]" 4
.IX Item "Program prog.vers daemon [arg ...]"
Specifies that connections to servers running Sun \s-1RPC\s0 program number
\&\fIprog\fR and version \fIvers\fR should be handed off to the the local
daemon \fIdaemon\fR.  \s-1SFS\s0 currently defines two \s-1RPC\s0 program numbers.
Ordinary read-write servers use program number 344444, version 3 (a
protocol very similar to \s-1NFS3\s0), while read-only servers use program
344446, version 1.  The read-only code has not been released yet.  The
\&\fBProgram\fR directive must be preceded by a \fBRelease\fR directive.
.PP
The default \fIsfscd_config\fR file is:
.PP
.Vb 2
\&  Release *
\&    Program 344444.3 sfsrwcd
.Ve
To run a different set of daemons when talking to sfs-0.3 or older
servers, you could add the following lines:
.PP
.Vb 3
\&  Release 0.3
\&    Libdir /usr/local/lib/sfs-0.3
\&    Program 344444.3 sfsrwcd
.Ve

The full documentation for \fB\s-1SFS\s0\fR is maintained as a Texinfo
manual.  If the \fBinfo\fR and \fB\s-1SFS\s0\fR programs are properly installed
at your site, the command \fBinfo \s-1SFS\s0\fR
should give you access to the complete manual.
