I wrote such a daemon (very simple) as an replacement for the kernel
watchdog. Of course it does a *software* reset and is even *less*
reliable than the kernel version.

If you don't have a hardware watchdog you must at least enable the
software watchdog (CONFIG_SOFT_WATCHDOG). Be aware the software
implementation can't be 100% reliable, as noted in the documentation.
