Honestly, a better solution would be an open-source IODD-type device, because sometimes I still meet old devices which do boot via USB DVD drives, but not flash drives.
But Ventoy is a second solid choice, especially with newer devices, where such limitations are basically non-existent :)
I personally have tried FreeBSD and some FreeBSD "distros" on the desktop, and have used BSD-based stuff as servers/single-purpose machines.
As a desktop system (user-centric use case), you notice how hardware support is sometimes problematic, especially on laptops. I personally had problems with NVIDIA GPUs, already a problem on Linux, being a big problem here as well, and don't mention WiFi (FreeBSD doesn't support 802.11ac and up currently) or Bluetooth. Software-wise, if your applications do not have a BSD version, well, then you are relying on Linux ports, which for desktop use isn't exactly great.
But, in servers/headless setups, BSDs are shining, with the most important things running rock-solid, stable and resource-friendly.
OPs function is indeed the Weierstrass function, but the "rollercoaster" here isn't a function at all, since there are multiple values per element, isn't it?
But isn't that behavior actually documented in the Arch wiki? At least when you manually install it, it lists packagekit-qt6 as being "not recommended".
I currently use Plasma 6 on both my laptop and my desktop, but XFCE has a special place in my heart, due to it being right in the middle between being lightweight with resources and still staying usable for a buffoon like me.
And the worst part: if you have actual needs for ML stuff - you kinda are stuck with nvidia cards, so you can't even switch when the need for upgrades arise.
I personally also welcome this change, as I have changed that setting anyway and of those people I know, they also changed that behaviour immediately. But as long as you can change it and it isn't forced on you to only use one method, it's great.
Well, my experience was always on and off:
In the past, I always had my phases of trying it out, be it dual-booting, or outright replacing my OS, but always went back to Windows after a couple of months at most due to some software being Windows-only and both VMs and WINE not being sufficient.
But this year, with Windows continuing to get worse (built-in ads, the fact that it eats 60+ GB on a base install, etc.) and me needing Linux for uni anyway: I made the jump and thanks to the work being done with stuff like Proton for games and FOSS software now being good enough for general productivity, I'm happier than ever.
Obsessed? I like customizability and being able to tinker around, but in the end, it's a tool like any other.
systemctl reboot --firmware-setup
That will reboot to UEFI setup instantly.
