Routing troubles(?); everything seems to work, though

Specifically, I’m getting this message from tailscale status from the install on a DigitalOcean droplet that I haven’t seen on any of my other Linux installs:

# Health check:
#     - dns: setLinkDefaultRoute: Unknown method 'SetLinkDefaultRoute' or interface 'org.freedesktop.resolve1.Manager'.

Anything I should be concerned about? And even if I shouldn’t, what’s it mean?
