There is no such necessity, fwiw. If gpg-agent or dirmngr need to be started,
there is .bash_login and such (and dirmng is started by gpg automatically
anyways). This dependence on systemd is an abomination because it breaks in so
many unpredictable ways. For example, with systemd 233, epiphany freezes when
started inside a container and systemd "is looping too fast" (and no, I'm not
reporting it upstream), but works if I manually kill systemd --user instance.

If you are not using Xorg, "pkill -9 systemd" in .bash_profile saves lots of
hair-pulling :)
