gpg-agent

How do you interpret the gpg-agent(1) man page? It says

--options file
       Reads configuration from file instead of from the default per-user configuration file.  The default configuration file is named ‘gpg-agent.conf’ and expected in the ‘.gnupg’ directory directly below the home directory of the user.

And later

gpg-agent.conf
        This is the standard configuration file read by gpg-agent on
        startup.  It may contain any valid long option; the leading
        two dashes may not be entered and the option may not be abbreviated.
        This file is also read after a SIGHUP however only a few
        options will actually have an effect.  This default name may be
        changed on the command line (see: [option --options]).
        You should backup this file.

Which IMO means that ~/.gnupg/gpg-agent.conf is read by default, even with --daemon. My experiments support this.

You are correct about the man page, I falsely recollected a specific detail there.

Regardless, my own practice has learned me that with --options explicitly pointing to the default file, SSH authentication using gpg-agent works, whereas without it, it does not. I have been testing and configuring this all afternoon, using fresh logouts, reboots and systemctl --user daemon-reload. This may be related to the circumstance that I'm starting gpg-agent from a systemd user unit. For example, the standard socket also isn't located in its documented place anymore. Reading e.g. [1]

With GnuPG 2.1 the need of GPG_AGENT_INFO has been completely removed and the variable is ignored. Instead a fixed Unix domain socket named S.gpg-agent in the GnuPG home directory (by default ~/.gnupg) is used. The agent is also started on demand by all tools requiring services from the agent.

In reality, these files are only found under "${XDG_RUNTIME_DIR}/gnupg/" when starting gpg-agent in daemon mode under systemd as user unit.

Do you have a non-default GNUPGHOME? Is the systemd unit exactly the same as on the wiki or can you show the customizations?

The default socket path changed in 2.1.13, see Talk:GnuPG and the note added in [2].

Lahwaacz (talk) 21:26, 14 July 2016 (UTC)

I haven't set GNUPGHOME, but perhaps the path to the GnuPG home is being normalized by GnuPG. It's a symlink in my setup.

'/home/sanmai/.gnupg' -> '/home/sanmai/secrets/.gnupg'

The systemd unit is the same as the one I've contributed to the Arch Wiki, i.e. has a single customization to the original one on the Wiki.

gpg-agent seems to behave correctly for me even when ~/.gnupg is a symlink - the config file is still loaded even without an explicit --options parameter. -- Lahwaacz (talk) 12:44, 16 July 2016 (UTC)

Today I had time to test again, and it works for me now without `--options`. I will correct the Wiki page now. Good catch!

Windows 10 ISO

I have looked at a few ISOs and they all have the install.esd, I haven't seen the install.wim in recent versions. In which Windows 10 ISO have you seen the wim format?

Kewl (talk) 20:16, 28 November 2017 (UTC)

Win10_1709_EnglishInternational_x64.iso

Sander Maijers (talk)

Then both esd and wim exist in recent Windows10 ISOs, I would remove the explicit reference to Windows 10 in the wiki

Kewl (talk) 07:45, 29 November 2017 (UTC)

Why do you believe install.esd exists? It doesn't in that ISO. If you have evidence this is true for more ISOs, feel free to specify that.

Sander Maijers (talk)

There are ISOs using wim and esd format: it depends how they are created, esd is the new format achieving better compression but is less friendly for deployment across networks using older windows versions Kewl (talk) 11:14, 29 November 2017 (UTC)
