If I remember correctly, the reason is that the observed behaviour is
that a driver sometimes will engage the watchdog without /dev/watchdog
is opened, triggered by one driver starting without anyone touching
/dev/watchdog. This caused the installer to stop after 1 minute. I
do not remember any more details. This was discovered a few years
ago, and I hope that crazy driver has been fixed in the mean time.
