- somewhat neater, more consistent and more readable output - possible to set any lvm.conf value: aux lvmconf "section/key = value" - LVM_TEST_NODEBUG to suppress the (lengthy) "## DEBUG" output - back-substitution on test output ($TESTDIR/$PREFIX -> @TESTDIR@/@PREFIX@) - support code moved from test/ to test/lib/ --> less clutter
