Topic: I found out about an ad-killer...
But! it only currently supports systemd and sysvinit.
The good news though is that it apparently is possible to make it work in openrc as well.
So likely it could be put on others as well.
It's called pi-hole.
I looked at it and the license is the only thing I am unsure of...
EUPL2 I think?
Well and the fact that a porting of the init scripts from sysvinit to openrc would be needed.
I don't know if this is pressing right now, but regardless, wondering if it is BSD portable, if not, it probably is of no importance anyhow.
But yeah, anyone who knows of an alternative for both now and HyperbolaBSD, let me know.
