glibc rebuilt inside the chroot; binutils died on `make info-recursive`, and makeinfo said why: its XS module was compiled against the host's perl 5.40 and our perl is 5.42. Stage-1 texinfo cannot run in there. Everything that builds .info documentation needs it, and it sat near the end of the list because that is where its own dependencies are, so stage 2 hoists it. linux-api-headers stopped earlier on `rsync: command not found` -- the kernel's headers_install runs it. apt had put it there and a build that finds its tool says nothing, so stage 1 never mentioned it. Its man pages come from Markdown the git tag does not pre-render, hence --disable-md2man. An inventory of the 110 apt packages against the chroot found 84 more such binaries. Most are documentation; the rest wait until something needs them. --- FR --- glibc a été rebâti dans le chroot ; binutils est mort sur `make info-recursive`, et makeinfo en donne la raison : son module XS a été compilé contre le perl 5.40 de l'hôte, or le nôtre est en 5.42. Le texinfo de l'étage 1 ne peut pas tourner là-dedans. Tout ce qui bâtit de la documentation .info en dépend, et il figurait en fin de liste, là où sont ses propres dépendances : l'étage 2 le remonte. linux-api-headers s'était arrêté avant sur `rsync: command not found` — le headers_install du noyau l'appelle. apt l'avait posé, et une construction qui trouve son outil n'en dit rien : l'étage 1 ne l'a jamais mentionné. Ses pages de manuel viennent d'un Markdown que l'étiquette git ne rend pas, d'où --disable-md2man. Un inventaire des 110 paquets apt face au chroot a trouvé 84 autres binaires du même genre. La plupart sont de la documentation ; le reste attendra qu'un paquet les réclame. Assisted-by: Claude Opus 5 |

Arch Linux s390x
A port of Arch Linux to IBM s390x mainframe architecture with systemd support.
Boots a full Arch Linux system on IBM mainframes (or QEMU s390x emulation) using a hybrid build: cross-compilation for the kernel, native s390x compilation on z/VM for userspace.
Quick Start
make container # build dev container (first time)
cp .env.example .env # configure z/VM access
make all # build kernel + initramfs + systemd
make test-systemd # boot it
What Works
- Arch Linux kernel 6.18.6-arch1 with Arch patches, cross-compiled
- Initramfs via modified mkinitcpio
- Static busybox built natively on z/VM, 2.3MB
- Root filesystem with ext4, switch_root to real rootfs
- Systemd as PID 1
Pacman, bash, and GNU coreutils are not yet ported.
Build System
The build uses two tiers:
Cross-compilation (x86_64 host): Kernel is built in a Fedora 43 container with s390x-linux-gnu-gcc. Initramfs is generated with a patched mkinitcpio that handles cross-architecture binary injection.
Native compilation (s390x z/VM): Busybox and systemd must be built on real s390x hardware. The z/VM system runs RHEL 9.6 with GCC 11.5.0. Scripts handle SSH deployment and retrieval automatically via .env configuration.
