Details:

I was having trouble using duplicity because gpg was trying to write to a
home directory it did not have permission to write to.  I ran duplicity a few
times as user scmelton to test things out.  It worked out fine then.  
However, when I ran it as the user other_user (a system user with a home
directory), it kept trying to write to /home/scmelton/.gnupg, which the user
other_user doesn't have permissions to do.  

I was finally able to work around this problem by using --gpg-options
"--homedir=/correct/permissions/directory/".  

However, when I ran the program as root directly it knew to put gpg files in
/root/gnupg.  

I suspect it might have something to do with sudo and duplicity.  When I
first log into my server I log in as scmelton, then sudo -i to root, then sudo
to other users as I need to to enter commands.  It might also have to do with
other_user being a system user that I can't actually log in as.

Command that didn't work: 
address@hidden: sudo -u other_user duplicity -v 9 /tmp/stuff/
rsync://address@hidden/test3/ 2>&1 | tee /tmp/output
