Even in the finish location, if any of the "law" fuckers scourging the open trackers, sends an abuse/dmca to Hetzner, you will have some explaining to do as they will raise it as a ticket and require an explanation as to what happened and what is your course of action to remedy it.
Source: my own experience about two months ago (used chatgpt to send them a neutral bussiness respone, worked like a charm)
Use vpn that allows port forwarding, or never touch public trackers at all, or both.
If I had to guess (and simplify too) I would say that that would be the difference between your freshly compiled C program just dying with sigsegv then getting (mostly) peacefully cleaned up, or otherwise your system either flat out dying on you or even worse, something somewhere getting corrupted and the system spirals out of control possibly thrashing data and even hardware.
I guess you are not renting that setup from someone, right? (colo?) I am asking because I have been renting a dedicated server from Hetzner for a few years now (one AX line, other from auction - got a good disc space with it) and with the price hike it's getting a bit costly (and can't self-host).
They take away dislike button, something I consider essential to navigate content, the algorithm is like a hyperactive drug dealer always ready to sell you the next big hit thing "you might like watch" and according to google itself the last YT revenue was 29.24 billion USD - so, it's not like they are going to sink without it isn't it.
So, yeah no thank you. They are doing extremely well, this is just squeezing every penny they can out of normal people so that the line goes up.
If they also stopped selling all my online data as a part of that subscription then I might consider it but it's hard to trust companies these days.
Oh and it seems this is not all of it, an ex-employee came out on twitter about sexual harassment, extremely bad work conditions and so much more.
The timing of it is weird to say at least but there's a lot.
As a (semi) power user I also use btrfs subvolumes to create "partitions" (single disk system, @root, @home, @docker), allows for making snapshots only for system or user data, etc.
All around, I love btrfs and I am never going back to journaling fs like ext4
Personally, halfway through I couldn't help myself but check if it's not april fools.
To me, it does not really vibe with factorio and it's making it needlessly more complex in a weird way.
