I can bootstrap an entire RKE2 VM (VM + RKE2 + join cluster) in like 5 mins with Salt (although I have no reason to think you couldn't do it with Ansible).
It's a cool project, but I didn't think the K3s part was the hard part.
I setup Linux Mint on an old HP laptop for my 7 year old. Things jist worked out of the gate. She doesn't use it for much else other than Roblox (Sober), Minecraft, YouTube, and OBS (to record videos - NOT stream), but it's teaching her how to use the keyboard and mouse and navigate by using something other than touch on a tablet. It also teaches her the basics of window managemen: minimizing, maximizing, putting them side-by-side, which has been a big adjustment but she's quickly gaining proficiency.
You absolutely do. Many coworkers will bug you to ask instead of doing their own research, bug you to chitchat, etc.
They can always book time with you, send an email/IM, etc if there's something they can't resolve on their own.
You have your own deliverables and being interrupted every 10 minutes with inane questions that a web search or a look at the internal wiki/KB would have resolved is not a productive use of anyone's time.
Also, forcing them to wait produces better quality, better researched questions as hopefully they should make some attempt to resolve things on their own.
