Summary

  • tailscale/github-action already passes --accept-routes on Linux, so the args: --accept-routes added in #9541 made tailscale up fail with "flag provided multiple times" and the "Join the tailnet" step never connected
  • Remove the duplicate from migrate.yml and docs.yml; the comment now says the action supplies the flag
  • Still gated by CI_DB_TAILNET, which is unset again, so this changes nothing until the staging route test is re-run

Type of Change

  • Bug fix (CI)

Testing

  • Reproduced on a staging workflow_dispatch of migrate.yml with CI_DB_TAILNET=true: "Join the tailnet" failed on the duplicate flag before checkout, so nothing reached the database; the variable was removed right after
  • Confirmed in the action source (v4.2.0) that it appends --accept-routes itself
  • actionlint -shellcheck= -pyflakes= clean
