Hi Martin & Maxime, I've tested if the system image builds after merging patches for the vboot-utils package. $ guix system build -s armhf-linux test.scm Unfortunately I don't own the ARM Asus C201 Chromebook so I can't test the live system. Could you Martin test please? I used commit 7af3b822178782d6598865e1d6a780a756dd0cb3. Petr
