[Nix-dev] Disabling gnome-keyring xdg autostart configuration

[Philip Potter]

I got a solution to my problem in the end!

I got stuck for a while because removing the /etc/xdg/autostart
symlink is basically impossible without recompiling the gnome-keyring
package.  However, the xdg autostart standard allows users to override
these values by putting files into ~/.config.

This askubuntu stack exchange answer captures it perfectly:
http://askubuntu.com/a/607563/559764

All I had to do was:
cp /run/current-system/sw/etc/xdg/autostart/gnome-keyring-ssh.desktop
~/.config/autostart
echo Hidden=true >> ~/.config/autostart/gnome-keyring-ssh.desktop

and now gnome-keyring's ssh component no longer starts, and I can use
gpg-agent as my ssh-agent again as desired.

I think there may be a way to do this more declaratively by instead
installing a package into the user profile which would drop the
required file into
~/.nix-profile/etc/xdg/autostart/gnome-keyring-ssh.desktop but I
haven't fully investigated this yet.
