Regardless of what Ubuntu has convinced themselves of, in this context the ZFS filesystem driver would be an unlicensed derivative work. If they don't want it to be so, it needs to be in user-mode instead of loaded into the kernel address space and using unexported APIs of the kernel.
A lot of people try to deceive themselves (and you) that they can do silly things, like putting an API between software under two licenses, and that such an API becomes a "computer condom" that protects you from the GPL. This rationale was never true and was overturned by the court in the appeal of Oracle v. Google.
Aggregate means two programs that are not combined and just live on the same filesystem. In the case of a filesystem driver, it's read into the kernel space and touches unexported APIs of the kernel and various kernel internals.
It is thus a derivative work.
So with all of this taken into account, what are your odds of dying in an asteroid strike in any given year? About 1-in-70,000,000.
So all-in-all I can assume I personally die from an asteroid strike about three times in 200M years while ignoring that the entire human species is wiped out twice.
And if I wanted the US Department of Transportation to handle this, based on personal risk to individual US citizens alone, they could spend about $30M a year on asteroid prevention.
The article sucks. It just says the risk is low and makes no attempt to compare the risk or the cost to anything else.
If I had to guess, I'd say heritable immunity.

As an aside (that means off-topic, guys) this looks like part of a fixed-point arithmetic implementation. It may not be as silly as you think.
Those genes are not expressed, and we don't have copies of those viruses floating around our bloodstream.
Probably, and for the most part. But we used to think the genome was mostly "junk DNA" before we understood that much of it was homeotic in function. It seems to me that virus copies would not be conserved over time unless they were serving some function.
