+Subject: [PATCH] Change location of sddm.conf.d to DATAROOTDIR
+
+/usr/lib is not a location that should be hardcoded - depending on
+distribution and architecture this can be different. So far, SDDM
+does not use this path unless the above conditions happen to make
+it coincide with the install location of its Qml modules.
+
+DATAROOTDIR is defined as: Read-only architecture-independent data.
+This seems to be a better fit for a system SDDM default config dir.

+Subject: [PATCH] Honor PAM's supplemental groups (v2) (#834, #1159)
+
+This moves the supplemental group initialization step from
+UserSession.cpp to the Backend system, so that the Pam Backend can
+inject additional supplemental groups via modules like pam_group.so.
+
+pam_setcred(3) assumes that it operates on an already initialized
+supplemental group list. However, PamBackend calls
+pam_setcred(PAM_ESTABLISH_CRED) earlier, at the start
+PamBackend::openSession, so a pam_setcred(PAM_REINITIALIZE_CRED) call
+must be issued to repeat the injection of PAM's supplemental groups.

+Subject: [PATCH] Revert "Honor PAM's ambient supplemental groups. (#834)"
+
+This reverts commit 1bc813d08b8130e458a6550ec47fb2bfbe6de080, which
+misuses PAM and leads to pulling in all of root's supplemental groups
+during session initialization instead of only adding PAM's extra
+groups. The problem was masked due to the root user not having any
+supplemental groups in some common contexts, like running sddm from a
+systemd unit.
