You=E2=80=99ll notice t= hat it automatically calls `sudo -n` on things, and that it requires `unbuf= fer`, which is usually installed alongside `expect`, so that it can capture= the output of `wg` retaining the color codes.

We have some wireguard running in server like infrastructure, where one
server serves dozens of "clients"

so instead of
peer: l9FxaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaU=3D
we would have something alike
peer: superhero downtown

some of you may be familar with batman-adv layer2 routing protocol,
there they also have a batctl which is working pretty similar to wg too= l.
there you can add a bat-hosts file which is doing the job, which totaly
works likes any hosts file
a normal hosts file maps ip to name,
a bat-hosts file maps mac addresses to name,
a wg-hosts file would map keys to name.

i found the sources for bat-hosts ( .c .h .sample ) here
https://downloads.open-mesh.org/batman/releases= /batman-adv-2019.5/batctl-2019.5.tar.gz

is this something maybe usefull to other also?
is there a chance to have this implemented by default?

thx for answers.
