The constant lying was the last straw for me. Every time I've dealt with a dealership, they've promised some deal or price that somehow disappeared off the table when the official paperwork came out. My wife and I walked out in the middle of the signing process once because there was so much bait-and-switch going on. Fuck these guys.
It sounds a bit nerdy, but dedicate some time just to learning a specific command once in a while. Start with something straightforward like ls. Read through the man pages and try out all the different options for it. After a while, you'll master quite a few commands and will be able to string them together to perform more complex tasks. It's definitely easier learning the system piece by piece like this. I used to learn by just jumping right in to a complex task, but I ended up with just a superficial understanding most of the time. Now days I try to be more deliberate about reading all the documentation and actually learning the tool/command/etc.
Also, Arch has the archinstall script that greatly simplifies the install process if you need it. You'll definitely learn more doing it manually though. I've been using Arch as my daily driver for a year now and I love it.
The last time I bought from a dealership was 12 years ago. The experience was so off-putting that I've exclusively gone to small used car dealers since then where the salespeople have been surprisingly more honest and less obnoxious. I felt like the dealership would've literally pickpocketed me if I had let my guard down.
Is this Alaska? I feel like every small town in Alaska has a parking lot like this.
