My one... battlefield with docker was trying to have a wireguard VPN system in tandem with an adguard DNS filter and somehow not have nftables/iptables not have a raging bitch fit over it because both wireguard and docker edit your table entries in different orders and literally nothing I did made any difference to the issue, staggering wireguard's load time, making the entries myself before docker starts (then resolvconf breaks for no reason). Oh, and they also exist on a system with a Qbittorrent container that connects to a VPN of its own before starting. Yay!
And that's why all of that is on a raspberry pi now and will never be integrated back into the image stacks on my main server.
Just... fuck it, man. I can't do it again. It's too much.
Odd consideration, but... I use 16Gb of ram and I have zero swap space and I've never seen a freeze in the three years this system has been assembled.
It could just be the way I tend to use my PC, light photo manipulation, some audio editing, some gaming just not AAA. I'm never stressing my system unless I'm opening a compressed file or rendering a video.
If you bag groceries, no one is going to give much of a shit whether you stay or go. On the upside, you probably won't care much either as most employers in 2023 are as replaceable as their employees.
Keep that in mind and you'll never get burnt, so long as you live somewhere with a varied enough employment scene for you to bounce around. If they're as replaceable as you, it's good peace of mind.
Some gospel goes so hard that it will grab you and make you start dancing.
