Although, at the moment, we do not yet require an event bus to be present, as we start to add more pieces we will want to ensure it is always available. Add a new constructor and replace existing uses of new(tsd.System) throughout. Update generated files for import changes. Updates #15160 Change-Id: Ie5460985571ade87b8eac8b416948c7f49f0f64b Signed-off-by: M. J. Fromberger <fromberger@tailscale.com>
