	# Disable random pool to work-around the slow random entropy

	# This is safe now because:
	# 1. We now only use hostapd for tests. (on test APs or in
	#    network.Ethernet8021X.* tests.)
	# 2. The random pool (and entropy estimations) seem to mostly be
	#    designed to guard against lack of initial entropy on a fresh
	#    boot, but they run at every startup. In the presence of many
	#    hostapd restarts, when "available entropy" gets drained by
	#    hostapd, /dev/urandom should still be seeded with enough entropy.
	# However, if we want to launch AP support in CrOS, it would be better
	# to re-evaluate this with security experts.
