Hi Yangwoo,

Thanks for your patch.

It looks like some image tests are broken by this patch. We get the
following error on the autobuilder:

RESULTS - parselogs.ParseLogsTest.test_parselogs: FAILED (9.86s)
RESULTS - systemd.SystemdBasicTests.test_systemd_failed: FAILED (3.69s)

This can be reproduced adding `IMAGE_CLASSES += "testimage"` to your
configuration with qemux86 or qemuarm64 MACHINE and poky-altcfg DISTRO.
Then just `bitbake core-image-full-cmdline && bitbake
core-image-full-cmdline:do_testimage` should be enough.

Can you have a look at the issue?

Thanks,
Mathieu
