It holds vt7.

As I said later in my earlier reply, I gave up on finding out its source...

"FirstVT" used to be an upstream variable but its was dropped in the
upgrade from 2.20 to 2.24 and the Debian maintainer seems to be
applying a patch in order to perpetuate it in Debian.

Anyway, I don't think that this a solution to the OP's problem, unless
I'm misremembering it. No matter what is set as FirstVT, you can end
up at a higher number after logging out and logging back in because
console-kit-daemon would've kept that VT allocated.
