Comment 20 for bug 1961079

Marking Focal target as invalid, we aren't expecting new release media.
Someone on Focal could still take the snap refresh and pick up the fix, when available, but there is nothing series specific about that.

Checking system-product-name is fine.

But is this really correct for every PowerEdge ever? https://en.wikipedia.org/wiki/PowerEdge says these things go back to 1996, presumably not all of them are valid? I'd like to avoid the sort of "subiquity doesn't boot on my really old hardware" type bug.
