[Duplicity-talk] no GPG passphrase

[Grant]

I've created a GPG keypair without a passphrase but duplicity still
prompts me for a passphrase.  How can I prevent the passphrase prompt
so I can automate the backup operation?

Reading my encrypted data still requires possession of the private key
even though there is no passphrase, correct?

BTW, can I pick files and folders from around the filesystem instead
of only specifying a single source location?
