#  USAGE       : isofs.sh <optional> -n (no clean up)
#
#  DESCRIPTION : A script that will test isofs on Linux system.
#                It makes ISO9660 file system with different options and also
#                mounts the ISO9660 file system with different mount options.
#
#  REQUIREMENTS:
#
#  HISTORY     :
#      06/27/2003 Prakash Narayana (prakashn@us.ibm.com)
#      07/28/2005 Michael Reed (mreed10@us.ibm.com)
#      - Changed the directory where the filesytems were being created
#        from /etc to copying /etc to /tmp/for_isofs_test/etc and
#        creating the file systems there
#      - Added the -n option to not remove the directories created for
#        debugging purposes
#      - Added -d option to specify a different directory to copy to /tmp
#        to make the file system
#
