		2dedfa	`This is the watchdog package for Fedora. It implements a userspace`
		2dedfa	`daemon which periodically pings (usually hardware) to tell the`
		2dedfa	`hardware that the machine is alive. If the hardware times out without`
		2dedfa	`receiving a ping, it assumes userspace is dead and reboots the`
		2dedfa	`machine.`
		2dedfa
		2dedfa	`There are several major classes of watchdog available:`
		2dedfa
		2dedfa	`- watchdog hardware implementing the Linux /dev/watchdog API`
		2dedfa
		2dedfa	`* drivers in /lib/modules/$(uname -r)/kernel/drivers/watchdog/`
		2dedfa	`* http://lxr.linux.no/linux/Documentation/watchdog/watchdog-api.txt`
		2dedfa
		2dedfa	`- softdog`
		2dedfa
		2dedfa	`* software watchdog (just runs inside the kernel)`
		2dedfa	`* implements the Linux /dev/watchdog API`
		2dedfa	`* won't help you if the kernel fails (obvious, right?)`
		2dedfa
		2dedfa	`- IPMI`
		2dedfa
		2dedfa	`* a heavyweight standard for all things server-management`
		2dedfa	`* separate Linux driver`
		2dedfa	`* ipmitool to control it`
		2dedfa	`* see README.watchdog.ipmi for how to use this daemon together`
		2dedfa	`with IPMI`
		2dedfa
		2dedfa	`You can also use watchdogs inside recent QEMU/KVM virtual machines.`
		2dedfa	`When running qemu, specify "-watchdog i6300esb" on the qemu command`
		2dedfa	`line (or use libvirt). Inside the guest, the i6300esb watchdog driver`
		2dedfa	`should automatically load and provide you with a Linux /dev/watchdog-`
		2dedfa	`compatible API.`
