I wrote a bootloader in Rust that boots Linux on IBM PowerVM — no C, no GRUB, no standard library. Just #![no_std] Rust talking directly to Open Firmware, parsing FAT and ISO9660, loading ELF kernels using UAPI BLS spec, and jumping to them with inline assembly. The hardest part? The firmware has a secret limit on memory allocations that nobody documents. https://siliconislandblog.wordpress.com/2026/03/18/booting-with-rust-chapter-3/

This is the most trandescental, ambitious, rich and promising collaboration effort that the GNOME Foundation and the KDE e.V. had ever done. Congrats to everyone involved in pushing this. https://github.com/PlaintextGroup/oss-virtual-incubator/blob/main/proposals/flathub-linux-app-store.md
