Now I guess it's because the order of execution. Previously, we first
start hotplug2 in preinit_essential, then insmod gpio-button-hotplug
(20_device_fs_daemons). Shortly after that the first state event
happened which would sync last_status and the actual state, but at which
moment no signal handler (USR1) was yet installed until later by
30_failsafe_wait.
Anyway, glad that this helps. ;)
