WARNING:
Don’t ever do this on a current bare metal system!
Even if you have everything backed up, plan on re-installing anyway, and just want to see what happens.
On a modern EFI system, recursively deleting everything (including the EFI path) has a chance of permanently hard-bricking your computer!
Just systemd things…
It’s not the 1970s anymore, why are you using the CLI?
Try administering M365/Azure using the admin web UI, and you’ll realize CLI usage is more important now than it ever was.
