# description: A software watchdog
#
# rc file author: Marc Merlin <marcsoft@merlins.org>
# Henning P. Schmiedehausen <hps@tanstaafl.de>
# 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.

# If you compiled your kernel with CONFIG_WATCHDOG_NOWAYOUT, you may

# will hang on umounting some remote nfs partition or for some other
# reason, and you may then want the kernel to reboot by itself.
# However, this means that if you stop watchdog, your system has one
# minute to reboot cleanly, or it will be rebooted by the kernel. If
# this behavior isn't what you want, just uncomment the following
