Four packages -- grep, gnupg, pacman and curl -- were failing on my own driver, not on the port. makepkg -f rebuilds but does not wipe $srcdir, so a re-run re-entered the previous attempt's tree: patch: ... already exists! Skipping patch. 1 out of 1 hunk ignored mkdir: build-curl-compat: File exists makepkg -C now cleans first. Worth stating plainly: those four looked like port problems for two full rounds, and were not. gcc: dropping sub-packages from pkgname was not enough. package_gcc() _picks files out for every front end regardless of what was requested, and _pick is a mv, so it fails on what was never built: mv: cannot stat 'usr/bin/gnat': No such file or directory The _pick lines for the disabled front ends are removed too. shadow needed libaudit-dev on the host -- one more makedepend that --nodeps hides until a build stops on it. --- FR --- Quatre paquets -- grep, gnupg, pacman et curl -- echouaient a cause de mon propre pilote, pas du portage. makepkg -f reconstruit mais ne vide pas $srcdir, si bien qu une reprise revenait dans l arbre de la tentative precedente : patch: ... already exists! Skipping patch. 1 out of 1 hunk ignored mkdir: build-curl-compat: File exists makepkg -C nettoie desormais d abord. A dire clairement : ces quatre-la ont eu l air de problemes de portage pendant deux tours entiers, et ne l etaient pas. gcc : retirer les sous-paquets de pkgname ne suffisait pas. package_gcc() extrait des fichiers pour chaque frontal quoi qu on ait demande, et _pick est un mv, donc il echoue sur ce qui n a jamais ete bati : mv: cannot stat 'usr/bin/gnat': No such file or directory Les lignes _pick des frontaux desactives sont retirees aussi. shadow reclamait libaudit-dev sur l hote -- un makedepend de plus que --nodeps masque jusqu a ce qu une compilation s y arrete.

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.
