--auto-features enabled turns every auto feature into a requirement, so installing a tool switches on code that never compiled here. Three of the fifty host packages did exactly that, and only one failed for the reason it named. expat had built clean the day before. asciidoc pulled docbook-utils in as an automatic dependency; it owns docbook2man, the third name in expat's find_program list, so docs defaulted ON twenty-nine hours before anything rebuilt. That tool is the SGML pipeline: on DocBook XML it writes nothing and still exits 0, and the mv it feeds is what reported the failure. Arch ships no xmlwf.1 either, so OFF is parity. systemd's split-bin probes the BUILD host's /usr/sbin. Ubuntu's is a real directory, so six binaries went where package() does not look -- and arch-meson's --sbindir is ignored, systemd computes its own. util-linux needed no option: poman-translate.sh greps po4a for the English "Discard" and this host answers "Rejet de". The locale belongs to the host, so it is pinned once on the makepkg line. --- FR --- --auto-features enabled fait de chaque fonction « auto » une exigence : installer un outil active donc du code jamais compilé ici. Trois des cinquante paquets hôte l'ont fait, et un seul a échoué pour la raison qu'il annonçait. expat compilait proprement la veille. asciidoc avait tiré docbook-utils en dépendance automatique ; il fournit docbook2man, troisième nom de la liste find_program d'expat, et la doc est passée à ON vingt-neuf heures avant toute reconstruction. Cet outil est le pipeline SGML : sur du DocBook XML il n'écrit rien et sort quand même 0, et le mv qu'il alimente est ce qui a signalé la panne. Arch ne livre pas xmlwf.1 non plus : OFF, c'est la parité. Le split-bin de systemd sonde le /usr/sbin de la machine de BUILD. Celui d'Ubuntu est un vrai répertoire, donc six binaires sont partis là où package() ne regarde pas — et le --sbindir d'arch-meson est ignoré, systemd calcule le sien. util-linux n'avait besoin d'aucune option : poman-translate.sh cherche le « Discard » anglais de po4a, et cet hôte répond « Rejet de ». La locale appartient à l'hôte : elle est épinglée une fois, sur la ligne makepkg. 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.
