# description: A software watchdog
#
#
# rc file author: Marc Merlin <[e-mail]>
#		  Henning P. Schmiedehausen <[e-mail]>
#	  Fix by: K. Yamato <[e-mail]>
#	    - Fix "${VERBOSE}="yes" line without no space characters.
#	    - Default daemon status is set to off in all run levels.
#          - The following settings are moved to /etc/sysconf/watchdog
#             + choice of watchdog or wd_keepalive as a deamon
#             + verbose option
#             + modules loading and unloading commands
#
#
# Note that even though chkconfig says that this should be run at runlevel 1,
# RH by default won't do this, so the RPM applies an ugly patch to 
# /etc/rc.d/init.d/single so that if you go from RL 3 to RL 1, watchdog is
# restarted anyway (if it's not, it can cause the kernel to reboot your machine
# depending on whether your kernel was compiled with CONFIG_WATCHDOG_NOWAYOUT)
#
# I have filed a bug with RH about this, and I hope they will change their
# single script to allow for other scripts to be run in RL 1.

# Source function library.
