tailscale up --auth-key=xxxx

FIX:
tailscale up --advertise-tags=tag:foo
tailscale up --advertise-tags=tag:foo --shields-up=true
tailscale up --advertise-tags= --shields-up=true  # explicitly mentioned good
tailscale up --shields-up=true  # ERROR: unmentioned thing is changing value
tailscale up [--init] --advertise-tags= --shields-up=true  # init is fine

// homerunner is Brad's shitty Docker wrapper after he got tired of running 
// HA nine-VM Kubernetes clusters. Earlier versions of this tried to use podman
// and fancy cloud-init and CNI stuff but then I decided to go to the other
// extreme and write something super specific to what I need and super dumb:
// run my containers from gcr.io, and use my home Ceph cluster for mounts/state.
//
// This primarily runs Home Assistant, HomeSeer, an MQTT server, and some cameras.
// And some omitted misc stuff.
