The problem here is not the OS, but the name of the machine.
Ive just tried this with two VMs, and when I joined one of them with --hostname TestVM1 I get the same behavior (MagicDNS not working), the other VM is unable to resolve the name, even if I manually type it out, using the correct casing.
But when I join it with --hostname testvm1 everything works as expected.

It looks like this is a problem in the tailscale client because the client expects the server to handle names differently.
When I join a new device to the official tailscale server and use --hostname TS-Test1 the server will set the machine name to ts-test1 and the OS Hostname to TS-Test1.

When I join a new device to headscale and use --hostname TS-Test1 the server will set the machine name to TS-Test1 and the OS Hostname to TS-Test1.

So for better compatibility with official tailscale, headscale should always change the machine name to lowercase.
