Windows 10 Enterprise LTSC 2019 has a 10 year support window, and subsequent LTSC versions, 5 years. If you can get your hands on one of these licences you would presumably continue to receive security patches. If the US government is somehow not running on this kind of licence, it would be pretty funny, but I’m sure Microsoft would be lenient and let them jump onto whatever compatible LTSC version given its an American company.
The browser versions aren’t too awful, if that’s an option.
Reddit death > installing mint on my second PC > realising I can run most of the games I play and installing mint on my main PC > start learning Rust as a first foray into programming in a long time > realise I want to go back to uni and study info tech to get out of my shitty marketing job > get a shitty second hand laptop off my parents that struggles to run windows and install endeavourOS to try something different.
It really is a slippery slope. When does it end???
Gentoo has systemd instructions right alongside openrc through the whole installation handbook. Pretty sure opensuse is systemd also.
