[Triage] Unraid Tailscale Integration breaks webui

[canonlp]

Describe the bug
When you install the pinchflat container from the community app store, on Unraid 7, you can add tailscale to the container itself. When you do that, you get no root privileges. If you remove the extra parameters --user 99:100, tailscale will install to the container, but the webui stops working.

To Reproduce
Steps to reproduce the behavior:

1. Install tailscale from app store
2. Turn tailscale integration on
3. Looks at the logs
4. See error

Expected behavior
The tailscale integration should install correctly

Hey there! Thanks for the report (:

I have a hunch that this is an interaction with Unraid <> Tailscale <> Docker that isn't related to Pinchflat necessarily (even though it's the one showcasing symptoms).

I'm not going to upgrade to Unraid 7 for at least a few months so I can't be very helpful in the immediate, unfortunately. I'll leave this issue open for a few days in case anyone has insight but I think the Unraid forums might yield better answers!
