Consider Oasis doas instead of OpenDoas
The doas
in main
is OpenDoas, it is a fork of OpenBSD's doas that got a bit invasive and it's a bit hard to understand exactly what's changed and how distant it's gotten.

OTOH there's Oasis doas
that's basically a patch applied to the upstream OpenBSD project making it work with musl and being the less invasive as possible.
https://github.com/oasislinux/oasis/blob/master/pkg/openbsd/patch/0016-doas-Port-to-linux-musl.patch
The timing seems great too. OpenBSD 6.6 was released Oct 17 and Oasis patch was updated Oct 18 to the new version.
