#=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.
