qubes-gpg-client-wrapper should ignore --homedir

[lechten]

Qubes OS version (e.g., R3.2):

R3.2

Affected TemplateVMs (e.g., fedora-23, if applicable):

All templates with Split GPG.

---

Expected behavior:

qubes-gpg-client-wrapper should remove the option --homedir, which makes no sense for offline GnuPG VMs.

Actual behavior:

qubes-gpg-client-wrapper passes the option to qubes-gpg-client, which exits with an unrecognized option.

Steps to reproduce the behavior:

qubes-gpg-client-wrapper --homedir ~/.emacs.d/elpa/gnupg/ -k

General notes:

qubes-gpg-client-wrapper removes keyserver-options with a comment on Torbirdy compatibility. Removal of homedir would increase Emacs compatibility (package management).

I think that there is a difference here in that Torbirdy forces the use of keyserver-options , but it's meaningless in the context of Qubes split gpg. That's why it's safe to remove it. There is no use of qubes-split-gpg where it could make any difference to operations.
But I can imagine someone setting up the backend with two gpg configs and attempting to use them both via split gpg by passing --homedir . This option isn't meaningless in this context: it's not supported. If it were simply stripped as you suggest they would be baffled by the results.
It's clear from documentation that the homedir option isn't supported by qubes-gpg-client, and the "unsupported option" message may lead someone to look there.
I'd have thought the right solution here would be to configure emacs not to pass the option.

I see. I'll propose a change to Emacs.
