I see. Sorry for confusing you. Here's what I wrote originally: TZ> It used to be possible to do TZ> GPG_AGENT_INFO=none gpg --decrypt foo.gpg TZ> GPG_AGENT_INFO=none gpg --batch --decrypt foo.gpg TZ> etc. TZ> but with GPG 2.x that seems to be disabled and the pinentry prompt pops TZ> up no matter what ....

So very specifically, the external pinentry prompt is preventing the `epa-file-cache-passphrase-for-symmetric-encryption' defcustom from operating properly. Ideally I don't want the initial graphical popup either--it's very annoying--but I can live with one popup. Ted
