That's a security problem on shared machines.

So I forget if I've mentioned this here, but what I do for the
gnome-ostree testing is at boot time, use a qcow2 overlay disk to write
a custom systemd service that exports the journal over a virtio-serial
channel.  Then I look for specific MESSAGE_IDs in the journal.

This is extremely reliable, no parsing of log messages etc.
