Mathieu Benoit 0963698d4b [FIX] xz has two doc toolchains, and libpsl needs data not a tool 
xz got past po4a and stopped on

  ../../../doxygen/update-doxygen: doxygen command not found

Two documentation toolchains in one package: po4a for the translated man pages,
doxygen for the liblzma API reference. --disable-doc is xz own switch, checked
present in configure before use.

libpsl stopped on

  make: *** No rule to make target
    /usr/share/publicsuffix/effective_tld_names.dat, needed by ...

publicsuffix-list is DATA. libpsl compiles the Public Suffix List into a lookup
table, so the list is an input to the build -- the first entry in this port whose
absence is neither a program nor a library, and it reads exactly like a broken
Makefile.

xz a passe po4a et s est arrete sur

  ../../../doxygen/update-doxygen: doxygen command not found

Deux chaines de documentation dans un seul paquet : po4a pour les pages de manuel
traduites, doxygen pour la reference d API de liblzma. --disable-doc est son
propre interrupteur, verifie present dans configure avant usage.

libpsl s est arrete sur

  make: *** No rule to make target
    /usr/share/publicsuffix/effective_tld_names.dat, needed by ...

publicsuffix-list est une DONNEE. libpsl compile la Public Suffix List en table
de correspondance : la liste est une entree de la construction — premiere entree
de ce portage dont l absence n est ni un programme ni une bibliotheque, et elle se
lit exactement comme un Makefile casse.

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.
