+Remove explicit set of UPOWER_CONF_FILE_NAME in up-self-test.c;
+instead the harness should set it.  In Guix we set it explicitly; the
+right thing is to use AM_TEST_ENVIRONMENT and regenerate the
+makefiles, but we can't regenerate because current autotools carp on
+some things, so we patch the Makefile.in instead.
+
+Also fix to not try to create /var/lib/upower if /var isn't writable.

+Patch by Andy Wingo <wingo@igalia.com>
