Mathieu Benoit ac5e5f3892 [FIX] groff: the figure and the document that includes it 
Emptying DOC_GNU_EPS stopped the GNU logo being built and left the document that
includes it:

  doc/webpage.ms:45: error: cannot open gnu.eps
  doc/webpage.ms:45: fatal error: PSPIC failed to include gnu.eps

Tenth time in this port, fourth of my own making. PROCESSEDEXAMPLEFILES_PS lists
webpage.ps and grnexmpl.ps, and the HTML variant directly above it is ALREADY
empty with its real value left as a comment -- groff configure empties that one
when the tools are missing. This does the same for PS, which is the decision
groff would have made had it checked.

--- FR ---

Vider DOC_GNU_EPS a empeche la construction du logo GNU et laisse en place le
document qui l inclut :

  doc/webpage.ms:45: error: cannot open gnu.eps
  doc/webpage.ms:45: fatal error: PSPIC failed to include gnu.eps

Dixieme fois dans ce portage, quatrieme de ma main. PROCESSEDEXAMPLEFILES_PS
liste webpage.ps et grnexmpl.ps, et la variante HTML juste au-dessus est DEJA
vide, sa vraie valeur laissee en commentaire — le configure de groff vide
celle-la quand les outils manquent. Ceci fait de meme pour PS : la decision que
groff aurait prise s il avait verifie.

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.
