I can confirm the issue with nixos-install running out of memory still happens even with the latest disko and nix tooilng

Hi all. Is there a way to ensure a certain disk is processed first in a disko configuration? I have a detached-header LUKS setup that encrypts my internal disks and writes their headers to an USB device. Disko does encrypt both devices, but it processes the USB last, and it does so by deleting the headers and repartitioning. Is there a way to ensure it formats the USB before installing the headers?

Sorry, I was looking for the priority option.
