# Linux/2/config - (based on Sun/5/config) 06/14/93
#     Developed by Advanced Research Corporation (R)
# 
#-----------------------------------------------------------------------------
# Linux/1/config - 04/20/99
# Linux/2/config - 04/20/99
# Linux/2/config - 10/09/99
#  Added the new check_neverlogin script
# Linux/2/config - 08/07/2002 - jfs change in LSGROUPS
# Linux/2/config - 11/25/2002 - jfs added PROCDIR and APACHECONFDIR
#                               also added code to determine Linux distribution
# Linux/2/config - 04/15/2002 - jfs added check for LSGROUP variable based
#				on fileutils version
# Linux/2/config - 06/20/2002 - jfs
#   Added patch provided by Ryan Bradetich to consider the 
#   case of RedHat's 7.1 fileutils:
#   $ ls --version
#   ls (GNU fileutils) 4.0.36
# Linux/2/config - 08/11/2003 - jfs - Added TCPD to exported variables and
#                  included HOSTALLOW and HOSTDENY
# Linux/2/config - 08/13/2003 - jfs - Removed LSCRIPTDIR since it is no 
#                  longer needed.
# Linux/2/config - 08/14/2003 - jfs - Added IFCONFIG
# Linux/2/config - 08/29/2003 - jfs - TESTEXEC needs to be defined first 
#                  for findcmd() to work
# Linux/2/config - 09/19/2003 - jfs - Define UUID (otherwise the new check 
#		of script permissions in initdefs will not work)
# Linux/2/config - 11/19/2003 - jfs - Define REALPATH and SNEFRU to $BINDIR
#	        and removed paths from findcmd() (patch from Ryan Bradetich)
# Linux/2/config - 01/11/2004 - rbrad - Add OMNIBACK_CELLSERVER and NTPCONF
# Linux/2/config - 01/15/2004 - jfs - Add XINETDCONF and INETDCONF
# Linux/2/config - 03/31/2005 - jfs - Changed GROUPC to GROUPSS
# Linux/2/config - 04/17/2005 - jfs - Added IPTABLES and CMP
# Linux/2/config - 05/20/2006 - jfs - Use TAIL properly (POSIX 1003.2-1992)
# Linux/2/config - 04/25/2009 - jfs - Use apache2 directory if available in Debian
# Linux/2/config - 01/14/2011 - jfs - Add /dev/shm and /lib/init/rw
#               to the writable filesystems (common tmpfs) (Debian bug #317329)
# Linux/2/config - 12/08/2011 - jfs - Add /run/, /run/shm and /run/lock
#               to the list of potentially writable filesystems as these
#               are commonly used as tmpfs (Debian bug #633060)
