What's that about?
poc
To further clarify, my system uses NVMe drives (/dev/nvme0n1 and
/dev/nvme1n1). So when I do dmesg > /dev/nvme1n1 as root, it overwrites
the first few hundred k of the NVMe disk, nuking the partition tables
and boot instructions and the like. Then when I reboot, it causes my
machine to PXE boot. You can nuke any drive by writing to the first few
sectors, so it could have been /dev/sda, /dev/vda, /dev/xvda, or whatever.
