Yeah, messing init script order is going to be hackish. You'd want to
add a hotplug script to react to when the NTP daemon syncs and apply
config after that. See the dnsmasq hotplug script for an example:
For WG it should be necessary to wait to configure the wg interfaces;
they just won't validate correctly until time is fixed. So you could
configure the interfaces in /etc/config/network and just have the
hotplug script add the default route (or whatever your needs are).

Sure, for people who are building their own hardware. Most people
