Very little honestly. Since it prefers rootless execution it can be trickier to deal with at times but once you can usually figure out the tricks to get around that, rinse and repeat.
Only when we show up. Most videos of kidnappings I've seen it's maybe a dozen citizens vs a dozen or slightly fewer agents. It needs to be more like 10 to 1 to properly discourage or defend their attacks without an all out assault.
Thanks for mentioning Wolf. I'm pretty happy with Sunshine but I do have those occasions where it can't stream because my monitor is turned off (upstairs) when I'm downstairs.
I would say listen but make your own choices and make mistakes (small ones). Parents are conditioned to protect their kids but that's a poor way for you to learn real life lessons.
I'd say that kind of thing should fall under a label of being "Classified". If it's something like a recruitment page for the Army that shouldn't need any kind of classification.
IDK about the RPi5 but earlier models don't do well with transcoding. You'll want to make sure to convert all of your videos to a format widely compatible with your clients. H264 is usually compatible with any device of the last 10ish years.
Bigger question is how long would you last? If you're benevolent then the people closest to you won't like you as their dictator because presumably you treat everyone equitably and don't keep a bigger piece of the pie for yourself and your confidants.
Even if it isn't an OpenWRT router if you have a hardwired server it can probably do a soft reset of the router or even modem (most modems I've used have had a web interface). If your router is in such a bad state it only responds to a hard reset it's probably reaching EoL.
Vanilla Debian on my old netbook does alright. I think my desktop is xfce.
Only thing better I've used is antiX. I moved away from that one though since they insist on not using systemd and it got to be too much of a hassle to work around (lots of packages assume systemd is your init). I think Void Linux is supposed to be similar.
If you want something dead simple then Boxes will do the trick. It doesn't give you nearly as much flexibility as virt-manager or LXC, etc. but I've found it to be capable.
In theory, yes, but it wouldn't be as significant as stopping it entirely (or pausing it instead of a hard start-stop). I only mention CPU limits because it's extremely easy to implement.
