+Subject: tests: Improve check for /proc/cmdline kargs
+
+On some systems there may be no root= argument, so the tests for
+appending /proc/cmdline arguments will fail. Instead, loop over each of
+the arguments in the host's /proc/cmdline and test that they're in the
+constructed config file. That will actually test if ostree added all of
+the system's /proc/cmdline args correctly. The regex isn't perfect here,
+but it's probably good enough for this test.
