OpenWRT has its own robust configuration system, which can do nice
things like avoid circular routing. For that reason, the set of tricks
that wg-quick uses are best avoided on those types of fully-managed
systems. That's why it's not included in the package. Perhaps it
should be, though, for people who would prefer to use quick ad-hoc
VPNs? Have you tried running it with any success?
As mentioned here, you may be able to replace some of the UP/DOWN
hooks with hotplug scripts, or possibly other hooks that are part of
the OpenWRT system. If nobody pipes up here, you might want to ask a
generic question on the OpenWRT list about generally how to execute
scripts on events in relation to network interfaces.
