Having had this issue, and following the links: Race Condition to the Forum
I used @sammo suggestion w/ @lleachii's IP suggestion and made a rc.local scheduled task. On top of that I added ntpdate package.
The picture demonstrates (in my case), that the last edited file on my system was quite dated (Fri Jun 1 time). Yet, the wg0 interface came online (sswg), time was restored, time was checked again by ntpd and what is not see thereafter is not important because I'm running online, VPN WireGuard default route.
The actual suggest fix, dated every file on my router making it unfixable.
Won't do This Again!
