- Added a new `--init-only` command line flag to `kube-proxy`. Setting the flag makes `kube-proxy` perform its initial configuration that requires privileged mode, and then exit. The `--init-only` mode is intended to be executed in a privileged init container, so that the main container may run with a stricter `securityContext`. ([#120864](https://github.com/kubernetes/kubernetes/pull/120864), [@uablrek](https://github.com/uablrek)) [SIG Network and Scalability]

E todas elas podem utilizar `yield`.

Neste caso, `dependency_c` precisa que o valor de `dependency_b` (nomeada de `dep_b` aqui) continue disponível para executar seu código de saída.

E, por outro lado, `dependency_b` precisa que o valor de `dependency_a` (nomeada de `dep_a`) continue disponível para executar seu código de saída.
