As with the text install test, there's an additional choice on
the 'Time settings' path compared to whatever image garret
developed the test on; right after 'Time settings' you have to
pick 'Set timezone' or 'Configure NTP servers'. So adjust the
test to handle this, just like we did there.
ARM actually doesn't have "install" test, but in install matrix,
there is test whether ARM disk boots into initial_setup. HDD is saved
after this test for Base tests.
