-=head1  syslog 
-=head2  syslog command that setsup the syslogd for MS, SV and nodes.
-        On MS, it makes sure all the xCAT messages goes to /var/log/messages file,
-               it enables syslogd receving logs from remote machies. 
-        On MS, it sends all the messages to MS,
-               it enables syslogd receving logs from remote nodes. 
-        On node,  it sends all the messages its master.  
-        Input: none, it takes the following environment variables: 
-           OSVER: possible values are sles10, fedora8, redhat5, aix etc.
