I asked since the Tor project don’t recommend using a VPN with Tor unless you’re an advanced user who knows how to configure both in a way that doesn’t compromise your privacy.
Since, in my setup, I have a use case for Tor and a use case for my own VPN, I would figure out what I risk this way:
My house —> My VPN elsewhere —> Tor
This was is the default in my setup and is very convenient. And I don’t have to think every moment about whether I’m connected to the VPN tunnel or not, before connecting to the Tor network.
