By enabling ‘services.openssh.startWhenNeeded’, sshd is started on-demand by systemd using socket activation. This is particularly useful if you have a zillion containers and don't want to have sshd running permanently. Note that socket activation is not noticeable slower, contrary to what the manpage for ‘sshd -i’ says, so we might want to make this the default one day.
