Adding syslog-ng to freenas (base) config yet to be done
Adding the freenas specific syslog-ng configuration file
Working around what is presumably a bug in syslog-ng
due to which it cannot send on udp port 514
and all bsd syslog clients must have it been sent form
this priviledged port, so we change its local port binding
to a different port (here 999)
Final (hopefully) changes and additions to add syslog-ng to
freenas. There might be more tweaks needed for Truenas.
