I'm trying to run use the
gpg tool to encrypt and decrypt files and I would like to know if it's possible to run this tool without it changing a user's global state. Specifically, running
gpg for the first time as a given user will cause it to create a
.gnupg directory and other artifact's in a user's home directory.
I've had some success in isolating the operation of this command from a user's public and secret key ring (see my Ruby gem at https://github.com/rcook/rgpg for how I do this) and this is the last remaining behaviour of
gpg I'd like to prevent.
