Most services in SLES and openSUSE, including syslog, are enabled in 
runlevels 2, 3 and 5 but not in runlevel 4. RHEL systems however follow 
the LFS and have services like syslog enabled in runlevels 2, 3, 4 and 
5. One of the patches I posted adds $syslog to the list of services that 
must be started before opensm is started. If the Default-Start runlevels 
specified in /etc/init.d/opensm do not match the runlevels in which 
syslog is started then chkconfig prints a warning when enabling the 
opensm service. Hence the above code to make the Default-Start runlevels 
of opensm match the Default-Start runlevels of syslog.

Bart.
