This removes a potentially increased boot delay for certain boot topologies where they block on ExecStartPre that may have socket activation dependencies on other system services (such as systemd-resolved and NetworkManager). Also rename cleanup to clean up in affected/immediately nearby places per code review commentary. Fixes #11599 Signed-off-by: James Tucker <james@tailscale.com>
