The need for -o was introduced indb6aedato set the -p flag for login. Setting -o overrides agettys built-in handling of arguments, so "-- \\u" was needed to mimic it. This broke the autologin-feature, since the -f (noauth) flag is not passed to login [1]. But with3d2157e, the -p flag is dropped, but the full change wasn't reverted, leaving autologin still broken - But for no reason since agetty does the right thing.
