sfscd_config(5)

NAME
sfscd_config - meta-client configuration

DESCRIPTION
The sfscd_config is really part of the SFS protocol specification. If you change it, you will no longer be executing the SFS protocol. Nonetheless, you need to do this to innovate, and SFS was designed to make implementing new kinds of file systems easy.

sfscd_config takes the following directives:

Extension string
    Specifies that sfscd should send string to all servers to advertise that it runs an extension of the protocol. Most servers will ignore string, but those that support the extension can pass off the connection to a new ``extended'' server daemon. You can specify multiple Extension directives.

Protocol name daemon [arg ...]
    Specifies that pathnames of the form /sfs/name:anything should be handled by the client daemon daemon. name may not contain any non-alphanumeric characters. The Protocol directive is useful for implementing file systems that are not mounted on self-certifying file systems.

Release {* | sfs-version}
    Begins a section of the file that applies to servers running SFS release sfs-version or older. * signifies arbitrarily large SFS release numbers. The Release directive does not do anything on its own, but applies to all subsequent Program directives until the next Release directive.

Libdir path
    Specifies where SFS should look for daemon programs when their pathnames do not begin with /. The default is /usr/local/lib/sfs-0.7.2. The Libdir directive does not do anything on its own, but applies to all subsequent Program directives until the next Libdir or Release directive.

Program prog.vers daemon [arg ...]
    Specifies that connections to servers running Sun RPC program number prog and version vers should be handed off to the the local daemon daemon. SFS currently defines two RPC program numbers. Ordinary read-write servers use program number 344444, version 3 (a protocol very similar to NFS3), while read-only servers use program 344446, version 1. The read-only code has not been released yet. The Program directive must be preceded by a Release directive.

The default sfscd_config file is:

  Release *
    Program 344444.3 sfsrwcd
To run a different set of daemons when talking to sfs-0.3 or older servers, you could add the following lines:

  Release 0.3
    Libdir /usr/local/lib/sfs-0.3
    Program 344444.3 sfsrwcd
