Third attempt on this package, and the first one written after reading
the file instead of assuming its shape. The two before it failed for
the same reason:
1. Skipping ./bootstrap. The source is a git checkout, not a released
tarball, so that removed configure itself:
PKGBUILD: line 43: ./configure: No such file or directory
2. Editing `bootstrap`. The check is not there. It lives in
bootstrap.conf, inside a shell function, and its message is built
from a $url variable -- which is why grepping the literal text
found nothing, twice.
The check is two lines: a grep for the serial and a die. Both are
replaced by a no-op that keeps the enclosing function valid, verified
against the real file before being committed.
grep is the only package here that INSPECTS its host's m4 macros. This
is not an s390x incompatibility: pkg-config 0.29.2 ships that serial on
every distribution, x86 included.
The hook checks BOTH that the patch step was inserted and that
./bootstrap is still invoked, so mistake 1 cannot come back silently.

Troisieme tentative sur ce paquet, et la premiere ecrite apres avoir lu
le fichier au lieu d en supposer la forme. Les deux precedentes ont
echoue pour la meme raison :
1. Sauter ./bootstrap. La source est un depot git, pas une archive de
version : cela supprimait configure lui-meme.
2. Modifier « bootstrap ». La verification n y est pas. Elle vit dans
bootstrap.conf, dans une fonction shell, et son message est
construit a partir d une variable $url -- d ou l echec, deux fois,
de la recherche du texte litteral.
La verification tient en deux lignes : un grep sur la serie et un die.
Les deux sont remplacees par une instruction vide qui laisse la
fonction valide, essai fait sur le vrai fichier avant de commiter.
grep est le seul paquet ici a EXAMINER les macros m4 de son hote. Ce
n est pas une incompatibilite s390x : pkg-config 0.29.2 livre cette
serie sur toutes les distributions, x86 compris.
Le crochet verifie A LA FOIS que l etape de correction est inseree et
que ./bootstrap est toujours appele, pour que l erreur 1 ne puisse pas
revenir en silence.

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.
