A página do manual de gpg-agent states:
The agent is usualy started on demand by gpg, gpgsm, gpgconf or
gpg-connect-agent. Thus there is no reason to start it manually.
In case you want to use the included Secure Shell Agent you may
start the agent using:
gpg-connect-agent /bye
The usual way to run the agent is from the ~/.xsession file:
eval $(gpg-agent --daemon)
Por um lado, isso me diz que "não há motivo para iniciá-lo manualmente" e, por outro lado, informa como iniciá-lo manualmente. - Eu entendi mal alguma coisa aqui?
No meu sistema, parece que tenho que iniciá-lo manualmente. Caso contrário, por exemplo, gpg-connect-agent reclama: can't connect to the agent: IPC connect call failed . - Preciso configurar alguma coisa para fazer o gpg-connect-agent iniciar o agente conforme indicado na man page?
Além disso, a página do manual de gpg-connect-agent diz:
--agent-program file
Specify the agent program to be started if none is running.
No entanto, gpg-connect-agent --help não lista essa opção e o comando também reclama se eu tentar usá-la.
Parece que a página man descreve um comando diferente, ou eu perdi alguma coisa importante?
Meu sistema é um Arch Linux atual. (Mesma situação em outra caixa debian).
