[Bug] Unable to rename nodes

[Haarolean]

Is this a support request?

• [x] This is not a support request

Is there an existing issue for this?

• [x] I have searched the existing issues

Current Behavior

A follow-up on this one: https://github.com/juanfont/headscale/issues/2646#issuecomment-2980824031

These hostnames are still visible/available in different places:

• logs
• device lists:

Given we still enconter them in these places, in order to understand what device that is, we have to either:

• allow adjusting this name (maybe merge them together)
• do not use them in logs & device lists

Expected Behavior

expected to see the human-readable names I've assigned myself

Steps To Reproduce

1. add mobile device, which's gonna be labaled as "localhost-sth"
2. observe it in the device list or logs

Environment

- OS: alpine
- Headscale version: 0.27.0
- Tailscale version: 1.84+

Runtime environment

• [x] Headscale is behind a (reverse) proxy
• [x] Headscale runs in a container

Debug information

Which mobile app are you using? Tried to reproduce this on Android (app version 1.88.4) and the name is updated almost immediately after headscale node rename -i 4 new-name.

Your example screenshot is confusing since the names are so similar, but I take it that haarlean-iphone is the name you have set, and haarlean-iphone1 is the "hostname", assigned by Headscale.

This is the expected behaviour, here from my test tailscale.com tailnet:

The original name is preserved in ().

As far as I can understand, you are able to rename nodes, but not past what we allow. In that case, I think this is no longer an issue and that we can close it?

I'm going to close this as "working as intended" as we prepare for 0.27.1
