Using dd to move-resize a partition by writing down the cylinder numbers and moving it piece by piece like some Tower of Hanoi. Wanted to add more space to my root after deleting the Windows partition, which happened to be first. There is apparently no built-in command to do that.

Booted up fingers crossed and everything worked.

Didn’t even need to translate to foot-pounds-force, since .50 BMG was already in freedom-loving units.
