In this season of sharing :-) last week I took Jason's reresolve-dns =
script as a reference and created a persistent background script =
"wireguard-monitor" that is started/stopped along side wireguard in our =
AstLinux project.

wireguard-monitor
=
https://github.com/astlinux-project/astlinux/blob/master/package/wireguard=
/wireguard-monitor

Currently wireguard-monitor only updates DNS endpoints when =
WIREGUARD_DNS_UPDATE=3D"yes" in the sourced /etc/rc.conf file.  =
wireguard-monitor can be stopped by deleting the PIDFILE.

One minor improvement over Jason's example is only DNS endpoints are =
updated, I test for manual IPv4/IPv6 addresses.  I also wrote it hoping =
someday [Peer-peername] will be a valid config syntax.

Note, there are several things specific to our project, such as we =
create /var/lock/wireguard.lock when wireguard is active, and we include =
/usr/lib/bash/sleep as a bash builtin, but there might be a few ideas to =
take away.
