#  USAGE       : autofs1.sh <disk_partition>
#
#  DESCRIPTION : A script that will test autofs on Linux system.
#  REQUIREMENTS:
#                1) System with a floppy device with a floppy disk in it.
#                2) A spare (scratch) disk partition of 100MB or larger.
#
#  HISTORY     :
#      06/11/2003 Prakash Narayana (prakashn@us.ibm.com)
#      08/01/2005 Michael Reed (mreed10@us.ibm.com)
#      - Added an check to see if a directory exists
#      - This prevents unnessary failures
#      - Correction to an echo statement
#      - Added an additional error message if a floppy disk is not present
#

#                41.46% - fs/autofs/dirhash.c
