# check_ctrlaltdel: looks for 'ctraltdel' line in /etc/inittab which would
# 		indicate that users can reboot the system
# 04.25.2001
# Javier Fernandez-Sanguino <jfs@computer.org>
#
# 12/08/2003 - jfs - Improved the check so that it takes into account
#                    the availability of /etc/shutdown.allow 
#                    (Debian Bug #603199)
# 10/19/2003 - jfs - Fixed check to avoid false positives (Debian Bug #215872)
# 08/09/2003 - jfs - Improved checked (might give false positives if comments
#		     where used)
# 07/25/2002 - jfs - Changed TigerInstallDir to .
