China still burns more coal every year than every single other country on earth put together.
This matters a lot, because it doesn’t matter that you’re “using electricity” if it’s coming from a big ol’ coal pollution factory.
In some ways, it’s preferable to directly use the coal in some applications – changing from chemical energy to thermal to movement to electricity back to thermal energy can be less efficient than just changing the chemical energy to thermal energy and using that directly.
I had to do it for my atom d2550s because of the odd hybrid x86/x86-64 systems they are. I had to install what ended up being linux mint debian edition 5 because that was the best way to get an OS on the odd bootloader system for various reasons, then upgraded to 6 to get to the latest debian, then I installed proxmox and removed all the debian stuff.
What do I do with something as weak as a pair of D2550s? Don’t you worry about that. I’ve found uses for both. :P
It’s an unusual use case, but it’s one reason you might need to install debian before proxmox.
