[Duplicity-talk] Error using launchd with duplicity

[Paul Morris]

Hi

I just came across your great software when looking for an S3 compatible 
backup. It's been working great in script form, however, I have a problem when 
using launchd to run it.

Looking at the stderr it seems there is a problem using pexpect in a 
non-terminal mode. A quick Google for the 'termios' error and it looks as 
though this condition needs to be handled within the app?

I'm trying to use launchd because it's new and has some neat features. I guess 
this isn't occurring under Cron? I can fall back to that if necessary so no 
major problem if this is a 'bug'.

Cheers
Paul
