NAME
sfscd - SFS client daemon

SYNOPSIS
sfscd [-d] [-l] [-L] [-f config-file]

DESCRIPTION
sfscd is the program to create and serve the /sfs directory on a client machine. Ordinarily, you should not need to configure sfscd or give it any command-line options.

OPTIONS
Stay in the foreground and print messages to standard error rather than redirecting them to the system log. Ordinarily, sfscd will disallow access to a server running on the same host. If the Location in a self-certifying pathname resolves to an IP address of the local machine, any accesses to that pathname will fail with the error EDEADLK (``Resource deadlock avoided'').

The reason for this behavior is that SFS is implemented using NFS. Many operating systems can deadlock when there is a cycle in the mount graph--in other words when two machines NFS mount each other, or, more importantly when a machine NFS mounts itself. To allow a machine to mount itself, you can run sfscd with the -l flag. This may in fact work fine and not cause deadlock on non-BSD systems. On Linux, the -L option disables a number of kludges that work around bugs in the kernel. -L is useful for people interested in improving Linux's NFS support. Specify an alternate sfscd configuration file. The default, if -f is unspecified, is first to look for /etc/sfs/sfscd_config, then /usr/local/share/sfs/sfscd_config.

FILES

(Files in /etc/sfs supersede default versions in /usr/local/share/sfs.)
