I don’t know Void-musl.

I don’t know if you can install libnss-mdns. If /etc/nsswitch.conf is not standard you also need to configure it.

Are you able to setup VM with Debian, so you can test with a standard environment?

My understanding is that dig does not support mDNS.

The most common way to use it via avahi-browse and avahi-daemon (mDNS service).

The following failes for me:

dig "pihole-s5.local" @224.0.0.251 -p 5353

The following works for me:

$getent hosts pihole-s5.local
192.168.2.10    pihole-s5.local

Zfs loves memory, vm loves memory.

If you have the funds for it I would get a minimum of 32 GB.
