xCAT already treats aarch64 as a target: BootPolicy hands an aarch64 node boot/grub2/grub2.aarch64, and grub2.pm aborts the node's grub configuration when that file is missing. xcat-dep neither ships the loader nor has an aarch64 manifest section, so mockbuild-all.pl stops at "no manifest section for target 'alma+epel-10-aarch64'" and an aarch64 node cannot netboot. grub2-xcat generates grub2.aarch64. riscv64 ships the distro grub2 UEFI image unchanged, but the EL grubaa64.efi carries the distro prefix (/EFI/<vendor>) and never finds the boot/grub2/grub.cfg-<HEXIP> that nodeset writes. %build runs grub2-mkimage -O arm64-efi -p /boot/grub2, the prefix grub2.ppc uses, from the noarch grub2-efi-aa64-modules, so every EL build host produces it. efi_uga stays out of the module list: it is x86 only and grub2-mkimage fails on it for arm64-efi. The image ships as aarch64-efi/grubaa64.efi and %post copies it to grub2.aarch64, the boot file of DHCP client architecture 11. The openEuler x86_64 repositories carry no grub2-efi-aa64-modules and openEuler has no aarch64 target, so that build ships without the image. mockbuild.pl checks the payload holds an AArch64 PE image. Release 3 -> 4. [alma+epel-10-aarch64] is a native EPEL target like x86_64 and ppc64le, not a forcearch cross-build like riscv64, and lists what [alma+epel-10-x86_64] lists: the EL10 service node perl set (t/servicenode_perl_deps.t), and the noarch x86 boot loaders, because an aarch64 management node serves the x86 nodes of a mixed cluster as a ppc64le one does. Those loaders now build natively on aarch64 the way they do on ppc64le. elilo-xcat ships its tracked prebuilt EFI payload, as on ppc64le: elilo cannot compile on aarch64. syslinux-xcat admits aarch64 in ExclusiveArch and takes the ppc64le path, installing the prebuilt bootloader blobs of the release tarball. Both noarch rpms built on aarch64 carry the same payload, byte for byte, as the published rh10/ppc64le ones. x86_64 and ppc64le builds are unchanged. t/aarch64_target.t holds the manifest cell to the EL10 x86_64 one and the loader pins to EL10 ppc64le, checks how the spec generates, ships, installs and removes grub2.aarch64, and where grub2-mkimage and the arm64-efi modules are installed, runs the spec's own command, checks the image is AArch64 with a /boot/grub2 prefix, and checks that adding efi_uga fails. aarch64 is EL10 only and is not in the --finalize-xcat-dep cross-arch genesis copy; BUILD.md says so. Validated: a full mockbuild-all.pl --target alma+epel-10-aarch64 on an EL10 aarch64 host builds and verifies all 22 required packages (7 minutes).
