Mathieu Benoit adb6c4f21d [FIX] four more packages that build without their documentation
git, xz, meson and pam. Each uses the project's own switch where one exists.

git is the one worth reading: `man` appears as a make target twice and
`install-man` twice, once each for git proper and once for contrib/subtree.
Removing the build targets and leaving the install targets gives "No rule to
make target 'install-man'", which reads like a broken Makefile. Four places,
again.

pam is different in kind from the others: xmllint EXISTS here, from our own
libxml2. It fails because pam validates its DocBook sources against DTDs that
are not installed and --nonet forbids fetching them. Shipping the DocBook XML
data would be a package; disabling the documentation is a flag.

git, xz, meson et pam. Chacun par l'interrupteur du projet lui-même, quand il
existe.

git mérite lecture : `man` figure deux fois comme cible make et `install-man`
deux fois, une paire pour git et une pour contrib/subtree. Retirer les cibles de
construction en laissant celles d'installation donne « No rule to make target
'install-man' », ce qui se lit comme un Makefile cassé. Quatre endroits, encore.

pam diffère en nature : xmllint EXISTE ici, il vient de notre libxml2. Il échoue
parce que pam valide ses sources DocBook contre des DTD non installées, et que
--nonet interdit de les chercher. Livrer les données DocBook serait un paquet ;
désactiver la documentation est un drapeau.

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.
