-#       overridden on the next connection. previously, you could provide a path
-#       to the agent socket in GPG_AGENT_INFO, but that was deprecated in GPG
-#       v2.1. instead, we must clone GNUPGHOME with links and replace the agent

+#
+#       gnupg commits fb88f37–aab8a0b moved sockets from GNUPGHOME by default
+#       to directories under /run. aab8a0b in particular solidifies the
+#       functionality shift to utilize systemd-logind's user runtime
+#       directories. if the dir isn't found, gpg will fall back to the homedir.
+#       since previous functionality allowed multiple homedirs with multiple
+#       sockets, a provision was added where changing GNUPGHOME will also
+#       change the socket dir to a hashed dir under the usual runtime dir.
+#
+#       utilizing this information, we can conclude:
+#         - on systems with user runtime dirs, changing GNUPGHOME will also
+#           give us a unique socket dir under the user runtime dir;
+#         - on other systems, the socket dir follows GNUPGHOME.
+#       therefore, the safest way to ensure unique sockets while not having to
+#       write specific logic for both scenarios is to simply change GNUPGHOME.
+#       the easiest way to do this is to create a new dir and link the contents
+#       of GNUPGHOME to the new home. we can then replace the agent sockets
+#       there with the forwarded one.
