#=head1  otherpkgs
#=head2  It gets the extra rpms and install/update them.
#        The environment variable OTHERPKGS contains the rpms to be installed/updated.
#        On MN, You need to:
#        1. put rpms under /install/post/otherpkgs/os/arch directory where 'os' and 'arch'
#           can be found in the nodetype table.
#        2. put the name of the packages to /opt/xcat/share/xcat/netboot(install)/platform
#           directory. The file name is one of the following:
#              profile.os.arch.otherpkgs.pkglist  
#              profile.os.otherpkgs.pkglist   
#              profile.arch.otherpkgs.pkglist  
#              profile.otherpkgs.pkglist
#   The install/deployment process will pick up the rpms and install them on the nodes. 
#   However, if the nodes have already installed and up and running, you can run the following
#   command to have the extra rpms installed:
#       updatenode noderange otherpkgs 
#

##  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
##         .                             .
##         .                             .
