I noticed that the new overlay tests fail as well, also with "path '/' not
found".
[Maybe] answering my own question: I think the problem may be that there
is no devicetree file and thus no devicetree root when booting through
efi (in other words, of_root is NULL). Would it make sense to skip the
tests in that case ?
