Hi, the third, zero sized partition "Gap1" gets indeed produced by libisofs. xorriso command -report_system_area does not show it, though. I am investigating. You may assume that this partition will not be produced in future xorriso versions. If the "Gap1" partition entry is suspected to disturb

Hi folks, I've been playing with the arm64 netinst build a little today, when installing a new machine. We *hadn't* been making them isohybrid thus far, and therefore when I simply dumped one onto a USB stick using dd it didn't work wonderfully. Due to the UEFI firmware being reasonably intelligen
