Having this enabled in-kernel will result in procd starting it during boot. This effectively solves the problem of the WDT in the Winbond W83793 chip potentially resetting the system during sysupgrade, which could result in an unbootable device. While the driver is modular, resulting in procd not starting the WDT during boot (because that happens before kmod load), the WDT handover during sysupgrade results in the WDT being started. This normally shouldn't be a problem, but the W83793 WDT does not like procd's defaults, nor the handover happening during sysupgrade.
