Someone in the youtube comments said so about an old diesel sounding like crap when only 2 out of 16 are firing. Must be something to it then. Maybe they can set it up so that its always a different 2 cylinders that do the heavy lifting (to even out the wear) while the others just sit there generating heat through friction. These engines must be massive and you can’t exactly roll them into a garage to loop the oil every time you need to start them up.
I can’t answer that question for that specific vehicle but as an F1 fan (or of its technical aspects rather) I can confirm that this is a thing. Engines built with such low tolerances that the pistons are completely stuck below operating temperature. Formula 1 cars have their oil warmed up and circulated from outside before a start can even be attempted without destroying the engine.
I asked ChatGPT and it seems to be giving a typically vague answer of listing multiple possible reasons like (as you guessed) taking a while to reach operating temperature, shoddy maintenance aka worn out parts affecting the procedure and the procedure itself possibly requiring certain “safety protocols” which need to be followed. Not sure if the latter is or has been a thing with such old locomotives but the other 2 sound plausible to me.
I can’t chime in on that specific angle but on exactly the opposite. I’d call myself an Arch guy, or Manjaro and Endeavour more specifically. But recently I started hearing more and more about Nobara, I own a Steam Deck and use GE Proton on there which is from the same guy so I said I wana try Nobara and I immediately felt at home. I’m not a big KDE fan but really the out of the box Nobara experience when it comes to gaming needs felt and feels so complete to me I really couldn’t complain about a single thing.
It obviously wont replace Arch in my homelab but I don’t think I’ll ever consider anything else besides Nobara for my desktop again. Point being I had next to zero practical Fedora experience up to that point. I tried Garuda before which is also Arch based and supposed to cater to gaming needs but with that direct comparison I now feel like Nobara is the only distro that truly gets gaming. It’s SteamOS for the KBM based Desktop.
If Mullvad is not available as a Snap or Flatpak (2 ways of installing self-sufficient auto-updateable packages without dependencies on other packages) then youre probably stuck with either adding this 3rd party repository (something which isn’t always recommendable either) which gives you automatic updates or using a .deb installation file like you would probably prefer and then manually retrieving updates when needed.
Anyways, others have told you as much already anyways. What I’d like to add is that it is definitely worth it to learn to work the terminal. I get that there are many people looking for an alternative to Windows or just an open approach to computing in general without looking for added complexity. Who wants complexity right? Whether such an experience exists in the Linux world is probably subjective. Ubuntu has definitely been a safe bet for the flattest learning curve required since its inception in 2004. But its still a niche thing that won’t experience user-friendly support from everyone (ie Mullvad).
So one could conclude that in order to truly be “free” (as in Free Software freedom) one needs to claim that freedom. You will removed things up. You will learn from your mistakes. You will regroup and you will grow as a user and dare I say PC-curious person.
Can you elaborate? That might be the answer OP is looking for.
