#=head1  ospkgs
#=head2  Used on Linux only. It installs/updates the rpms thta are from OS distro. 
#        The environment variable OSPKGS contains the rpms to be installed/updated.
#        On MN, You need to:
#        1. update the rpms under /install/os/arch/... directory where 'os' and 'arch'
#           can be found in the nodetype table.
#        2. put new package names to /install/custom/netboot(install)/platform or 
#           /opt/xcat/share/xcat/netboot(install)/platform
#           directory. The file name is one of the following:
#              profile.os.arch.pkglist  
#              profile.os.pkglist   
#              profile.arch.pkglist  
#              profile.pkglist
#  You can run the following commands to install/update the rpms from os distro.
#       updatenode noderange ospkgs 
#       updatenode noderange -S    (this one intslls/updates rpms from os distro as well as otherpkgs)
#       updatenode noderange -P "ospkgs --keeprepo"  (this one will preserve the original repositories when installing/updating the rpms. )

# pmatch determines if 1st argument string is matched by 2nd argument pattern

pmatch ()
{

  esac

  return 1          # non-zero return code means string not matched by pattern

##  The following routines implement the notion of an array.
##  The POSIX shell does not support arrays.
##  With these routines, an array conceptually called "my_array" is implmented using the following series
##  of variables:
##
##      my_array__ARRAY_HIGH_INDEX  - holds the highest index used in the array
##      my_array__0   - value for element 0 of my_array: my_array[0] in standard array notation
##      my_array__1   - value for element 1 of my_array: my_array[1] in standard array notation
##         .                             .
##         .                             .
