+"""Integration test for the package update upgrade install module.
+
+This test module asserts that packages are upgraded/updated during boot
+with the ``package_update_upgrade_install`` module. We are also testing
+if we can install new packages during boot too.
+
+(This is ported from
+``tests/cloud_tests/testcases/modules/package_update_upgrade_install.yaml``.)
+
+NOTE: the testcase for this looks for the command in history.log as
+      /usr/bin/apt-get..., which is not how it always appears. it should
+      instead look for just apt-get...
