Creating and shipping a UKI means that people can just write it to a USB drive that has a vfat partition marked as an ESP. As long as the filename is BOOTX64.EFI, modern x86_64 hardware will automatically find and boot that if no other working EFI entries can be found. Since the kernel commandline is embedded in the UKI, there's no manual/error prone setup to be able to boot the file with any required/extra arguments. https://github.com/zbm-dev/zfsbootmenu/wiki/Portable-ZFSBootMenu https://github.com/zbm-dev/zfsbootmenu/wiki/Portable-ZFSBoot...
