dirmngr system integration

==========================

Since 2.1.x, gpg and most related processes will auto-launch dirmngr

if needed. These auto-launched processes will inherit whatever

environment they started from, and they will not terminate

automatically.

systemd

=======

Since 2.1.17, users on machines with systemd will have a dirmngr

process launched automatically by systemd's user session, upon first

access of the standard socket. systemd will also cleanly tear this

process down at session logout.

Users who don't want systemd to manage their dirmngr in this way for

all future sessions should do:

systemctl --user mask --now dirmngr.socket

Doing this means that dirmngr will fall back to its manual mode of

operation. (This decision can be reversed by the user with "unmask"

instead of "mask")

See systemctl(1) for more details about managing the dirmngr.socket

unit.

Manual dirmngr startup and teardown

===================================

Any user who wants to launch dirmngr manually (e.g., to talk to it

with a tool from outside the GnuPG suite) and is *not* using systemd

should first ensure that it is launched with:

gpgconf --launch dirmngr

If dirmngr is launched manually or automatically (but not supervised

by systemd), you also probably want to ensure that it terminates when

your session ends with:

gpgconf --kill dirmngr

If you're not using systemd, you may wish to add this command to your

session logout scripts.
