bug#24783: 25.1 launchs gpg-agent --homedir as ~/.emacs.d/elpa/gnupg

[Fkqqrr]

I am running Emacs 25.1 under Gentoo.

Each time I run `list-packages', Emacs 25.1 launchs Gnupg-2.1 gpg-agent,
but the `--homedir' argument is set to `~/.emacs.d/elpa/gnupg' though I
have it to `~/.gnupg' in `~/.gnupg/gpg-agent.conf'. Obviously, Emacs
25.1 fails to respect `gpg-agent.conf'.

However if `gpg-agent' is launched before `list-package', Emacs 25.1
will respect that.

bug#24783: 25.1 launchs gpg-agent --homedir as ~/.emacs.d/elpa/gnupg

According to `(gnupg) Agent Options':

'--homedir DIR'
     Set the name of the home directory to DIR.  If this option is not
     used, the home directory defaults to '~/.gnupg'.  It is only
     recognized when given on the command line.

So setting this in gpg-agent.conf wouldn't work (which makes sense,
since you need to know the homedir in order to find the configuration
file).

There is some code package.el that changes the gpg homedir:

(defun package-import-keyring (&optional file)
  "Import keys from FILE."
  (interactive "fFile: ")
  (setq file (expand-file-name file))
  (let ((context (epg-make-context 'OpenPGP))
        (homedir (expand-file-name "gnupg" package-user-dir)))
    (with-file-modes 448
      (make-directory homedir t))
    (setf (epg-context-home-directory context) homedir)
    (message "Importing %s..." (file-name-nondirectory file))
    (epg-import-keys-from-file context file)
    (message "Importing %s...done" (file-name-nondirectory file))))

Perhaps this setf should be a letf instead?

I would say that is an expected behavior.  package.el maintains keys
under ~/.emacs.d/elpa/gnupg, not ~/.gnupg.  If you want to configure
anything for gpg-agent started by package.el, you should add it to
~/.emacs.d/elpa/gnupg/gpg-agent.conf, not ~/.gnupg/gpg-agent.conf.

Really?  If it is the case, it must be a bug in GnuPG.  As far as I know
it allows multiple gpg-agent instances for each --homedir.

If that's package.el's `wanted' feature (default in
~/.emacs.d/elpa/gnupg), it does not harm to system. I couldn't
figure out why not just use system default location.

Similarly, SSL certificates (of mail servers) are stored in
.emacs.d/network-security.data insead of ~/.gnutls/known_hosts

GnuPG does allow multiple gpg-agent insances. You can check that
by:

1. list-packages in Emacs, then an instance created under
~/.emacs.d/elpa/gnupg;
2. C-x C-f to opens a gpg file, then another instance (system
default one) created under ~/.gnupg/
