Unfortunately I had to keep `linux-client` to get the compatibility tests to pass. #4578 aims to remove that package. Please add to this list if you think of anything: ```[tasklist] # Things that may break that CI/CD won't catch - [ ] Github release artifacts - [ ] Knowledge base - [ ] Docker images - [ ] Docker containers - [ ] Existing `linux-client` users - [ ] Anything that downloads ghcr artifacts - [ ] Nix (Not sure if it's built in CI. It had a merge conflict) ``` Refs #4515, and #3712, #3782 I think this is what Thomas and I agreed on in Slack / Github --------- Signed-off-by: Reactor Scram <ReactorScram@users.noreply.github.com> Co-authored-by: Thomas Eizinger <thomas@eizinger.io>

# Debian default DNS setups
|
|
|
|
## Conclusion
|
|
|
|
As of Feb 16th, the code in Firezone will probably work well on Ubuntu. On Debian we'd need to either ask for `systemd-resolved` to be installed, or fall back on rewriting `/etc/resolv.conf`, since we don't cooperate with NM yet.
|
|
|
|
- Ubuntu 20.04 has `systemd-resolved` built in to `systemd` itself. We can ignore NM for now and call `resolvectl`
|
|
- Debian 12 with XFCE has NM and dnsmasq. NM manages resolv.conf by itself without `systemd-resolved`.
|
|
- Debian 12 CLI just seems to have a fixed resolv.conf at install time. No NetworkManager, no dnsmasq, no `systemd-resolved`.
|
|
|
|
Derived from this, with some redactions for brevity and blank lines for readability:
|
|
|
|
```bash
|
|
uname -r; dpkg -l | grep dns; dpkg -l | grep resolv; dpkg -l | grep network-manager; cat /etc/resolv.conf; which resolvectl;
|
|
```
