bind = "auto": wait for the default route instead of failing at boot - #3

Conversation
network-online.target can be reached by other links (CX7, tailscale0) before
the LAN has its default route. resolve_bind("auto") then raised, the service
exited with status 2, and RestartPreventExitStatus=2 kept it down after a
reboot. Poll for up to 120 s before giving up.

Problem
After a reboot of both sparks (2026-10-22), the console on spark1 and the agent on spark2 stayed down:
network-online.targetwas reached once the CX7 links andtailscale0were up, before the LAN had its default route. Exit status 2 is inRestartPreventExitStatus, so systemd never retried.Fix
resolve_bind("auto")now polls for up to 120 s for the default-route interface to get an IPv4 address before raising. A real misconfiguration still exits 2 after the wait.Tests
test_resolve_bind_auto_waits_for_route(route appears on the third poll).🤖 Generated with Claude Code
