+In Guix, this library is installed in a separate directory in the store,
+and it's typically not installed system-wide in a fixed directory. Add
+the store path to the set of default directories so dependents can find

-Subject: [PATCH] evbuffer_add: Use last_with_datap if set, not last.
-
-evbuffer_add() would always put data in the last chain, even if there
-was available space in a previous chain, and in doing so it also
-failed to update last_with_datap, causing subsequent calls to other
-functions that do look at last_with_datap to add data in the middle
-of the evbuffer instead of at the end.

-Fixes the evbuffer_add() part of issue #335, and the evbuffer/add2 and
-evbuffer/add3 tests, and also prevents wasting space available in the
-chain pointed to by last_with_datap.

-Subject: [PATCH] Allow negative uids/gids in PolkitUnixUser and Group objects
-
-(uid_t) -1 is still used as placeholder to mean "unset". This is OK, since
-there should be no users with such number, see
-https://systemd.io/UIDS-GIDS#special-linux-uids.
-
-(uid_t) -1 is used as the default value in class initialization.
-
-When a user or group above INT32_MAX is created, the numeric uid or
-gid wraps around to negative when the value is assigned to gint, and
-polkit gets confused. Let's accept such gids, except for -1.
-
-A nicer fix would be to change the underlying type to e.g. uint32 to
-not have negative values. But this cannot be done without breaking the
-API, so likely new functions will have to be added (a
-polkit_unix_user_new variant that takes a unsigned, and the same for
-_group_new, _set_uid, _get_uid, _set_gid, _get_gid, etc.). This will
-require a bigger patch.
-
-Fixes https://gitlab.freedesktop.org/polkit/polkit/issues/74.
