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.


Currently wireguard-monitor only updates DNS endpoints when WIREGUARD_DNS_UPDATE="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.
