It is a buggy test case.  It is meant to evoke a "ERROR: Module name
... is too long." message, which it does if the testsuite is being run
as root.  Without that, you get instead the "ERROR: .... setuid"
message, which is absolutely a bug as we shouldn't get that far.

That's true to an extent - but even with .log analysis, you'd have
gotten either one ERROR: or the other, one being a false positive.
