[Csync2] Csync2 via xinetd does not work

[Dan Falconer]

Same results as before.  The "lsof" and "netstat" commands indicated 
that the process was running & listening.  When I telnet to each server 
using the appropriate port, it worked as expected.

It seems like running in xinetd mode causes the daemon to not know where 
it's configuration file is.  Like it can't find the appropriate key, so 
the SSL handshake fails.

The configuration file is below (scrubbed):

    # Csync2 Configuration File

    # csync2(1) man page
    group ftpsync

    {
             #
             # comments that say "(see x.y.z)" refer to chapter x,
    section y,

             key /etc/csync2/csync2.key;

             exclude _*.tgz;

    (see 3.4.6)
             backup-directory %MNT%/csync2-backup;
             backup-generations 3;
    }
    prefix MNT
    {
             on linux3.foo.local:      /sync;
             on *:                           /data01;
    }
