1) if you need to wait for your AP
use e.g. 'ubus -t 30 wait_for hostapd.wlan0'
to wait for it up to 30 secs to show up
2) to synchronize PROCD startup-scripts
add a service_started() method in your scripts that does busy-polling for
procd/netifd to bring up services. This blocks subsequent init-scripts from being
executed before your current script is done.
Some kind of dependency tracking within procd would help for sure (e.g. 'start
this service only after services x+y are running'), but given how services are
handled as independent instances now, this would add lots of complexity to modules
that must not fail.
