Auto-approve Tailscale exit-node routes from tag:homelab devices - #9
Merged
Conversation
Adds `autoApprovers.exitNode = ["tag:homelab"]` so any tagged homelab device that re-runs `sudo tailscale up --advertise-exit-node` is auto-approved as an exit node with no admin-UI click. Tag-gated by design — only nodes we've already vouched for via the auth-key + ansible flow can self-approve exit routing. Surfaces: pi-zero-exit lost its exit-node advertisement at some point post-2026-05-12 (ExitNodeOption=False, Tags=[]). Re-running the up command on the device will restore advertising; with this ACL change in place, the 0.0.0.0/0 + ::/0 routes auto-approve instead of waiting for a human in the admin UI.
