so can i take it as your concession that the vsyscall feature is indeed
a security problem and it's being randomized/(re)moved for security reasons?

in that case the naming of this feature is correct and you have no reason
to call it "borderline security FUD". so make up your mind!

how can the name be "borderline security FUD" but what the name refers
to not be that? you see, we name things for a reason, mostly because
we think the name has something to do with the thing it names, duh?
