    Actualicé mi @archlinux y pasó lo que tenía que pasar:

    - comenzó a reiniciarse de forma random.
    - actualicé de nuevo: nueva versión del núcleo.
    - se apagó, se rompió el grub.
    - reinicié con un live.
    - no estaba el núcleo compilado en el /boot.
    - hice chroot al / de mi instalación.
    - reinstalé el núcleo Linux, los firmwares, el grub, su configuración, y creé el ramdisk.
    - reinicié y acá está andando.

    ... nada del otro mundo, bah 😅

    When two Hetzner servers died at the same time

    On May 12, 2026, two of my Arch Linux + LUKS servers at Hetzner became unreachable at the same moment. Both had been running for 4+ months without issue. Both had received the same pacman -Syyu the day before, but had stayed on the old kernel until the morning the websites stopped responding. I rebooted — SSH never came back. nmap -Pn -p 22 showed filtered from anywhere. No ping. No banner. The Hetzner Robot panel insisted the hardware was fine.

    Several hours went into hypotheses that turned out to be wrong:

    • The encryptssh initcpio hook referencing a /usr/lib/initcpio/udev/11-dm-initramfs.rules file that no longer exists. Real bug, no boot impact — the initramfs rebuilds anyway.
    • PermitRootLogin no in sshd_config. Real misconfiguration, fixed it, didn’t help. A refusing sshd shows closed, not filtered.
    • Predictable interface-naming drift after the systemd 260 upgrade. Patched the .network config to match by MAC. Useful hardening; not the cause.
    • Stale GRUB stage1 + core.img in the MBR. Arch never re-runs grub-install after a grub package upgrade. Refreshed it. Still filtered.
    • Kernel 7.0.5 regression. Downgraded to 6.18.3, the kernel that had run for 4 months. Still filtered. So the kernel itself wasn’t it either.

    The clue was in the persistent journal: a single recorded boot from December 31 to May 12 10:13 UTC, and absolutely nothing after. Every reboot since the upgrade was failing before systemd-journald could flush to disk — so the failure had to be in the initramfs, before the root filesystem was even mounted.

    What it almost certainly was

    Hetzner Dedicated servers configure the initramfs network with ip=dhcp on the kernel command line. That depends on Hetzner’s DHCP server replying to whatever request format the current kernel sends. Somewhere between kernel 6.18 / iproute2 6.18 and kernel 7.0 / iproute2 7.0, the request format changed enough that Hetzner’s DHCP stopped responding. Effects:

    • Old kernel at runtime kept the interface already configured (Phase A — 32 hours of healthy operation after the package upgrade).
    • New kernel cold-boots, hits DHCP, never gets an IP, dropbear cannot listen, port 22 stays filtered.

    Hetzner’s own documentation has been quietly moving away from ip=dhcp toward static IPv4 in the kernel command line. The fix is exactly that:

    GRUB_CMDLINE_LINUX="cryptdevice=/dev/md1:cryptroot ip=A.B.C.D::GATEWAY:255.255.255.255:hostname:eth0:none"

    One line in /etc/default/grub, grub-mkconfig, reboot. No more dependency on Hetzner’s DHCP responding to whatever your current kernel sends.

    Why it matters for anyone running this stack

    If you run Arch on Hetzner Dedicated with full-disk encryption and remote unlock via dropbear, the ip=dhcp shipped by installimage is a latent bug. It can keep working for years and then break overnight, on every machine you have, after a routine pacman -Syyu. The static-IP version is what Hetzner now recommends and removes the entire dependency.

    Tooling

    While debugging, I turned the whole rescue / chroot / diagnose / fix workflow into a Python CLI (hal) — including hal fix static-ip, which derives the static cmdline directly from your existing systemd-networkd .network file:

    → github.com/kevinveenbirkenbach/hetzner-arch-luks

    Single command, idempotent, reversible (the original /etc/default/grub is backed up to .hal-backup). If you’re on this stack, switch to static IP before the next kernel upgrade catches you.

    Deux nouveaux hooks pour #mkinitcpio sur #ArchLinux, suite à la MAJ faite cette nuit : [systemd] et [sd-vconsole]

    Conséquence liée ? À l’allumage, ce matin, entre les écrans “Chargement de Linux…” et celui d’ouverture de session, toute la phase de démarrage de systemd se fait… en écran noir complet, à l’aveugle (il n’y a plus la ligne “/dev/sda…”, ni de simple curseur texte “_” gris) ! C’est perturbant, ce changement non sollicité… >__<

    (2/2)

    Not something I did, but something that happened:
    - Friday's v39 release means that my improvements are now in a stable release. should no longer have to patch mkinitcpio!

    What I'm doing today:
    - Following up with the gotk4 prep PR
    - Working through some of the packaging backlog.
    - Working through some of the Parabola email mailinglist backlog

    Challenges/blockers:
    - Waiting for @amerl to email me some files I'd saved on his laptop

    Apparently there was an issue on in package, where due to some races w/ , mkinitcpio failed to discover devices and has generated the disk w/ no modules.
