Admin Console Install script causing installation to fail when seperate partitions exist for /var and /opt file systems, is sufficient but but the /var and /opt file systems are too small

VMWare platform used to install NAM components on RHEL (although happens with SLES) and two different 
disk are used for partitioning.   The first disk is smaller and is used to install the OS. The key file 
system partitions (/, /opt, /tmp, and /var) are all inside a volume group on this first disk.

The second disk (100GB in size) is used for the Application and a second volume group with /opt/novell, 
/var/opt/, /opt/volera,  and a few others in a second volume group.

With this setup, the install would fail due to the mountpoint checks run:

 echo "The mountpoint $mntpoint needs $SPACE_NEEDED of free space, but only has
$SPACE_AVAIL available." | tee -a  "${log_file_path}"

One could workaround the issue by commenting out lines 475-487 of the "install_utility_functions.sh" script
This check fails because it simply checks for the /opt partition - in our case the actual /opt partition is 
only 62mb in size but /opt/novell is 15GB and /opt/volera is 10gb and /var/opt/ is 64GB in
size. 

Although the install does not check, it needs to verify whether partitions below /opt/ and /var/
exist and have enough space.

/opt/novell - 1GB             
/opt/volera - 5MB         
/var/opt/novell - 1GB                 
/var - 512MB  
/usr - 25MB 
/etc - 1MB     
/tmp/novell_access_manager - 10MB                        
/tmp - 10MB
/  - 512 MB
