SepiaOS v2026.8.1

A complete SepiaOS card for Pi Zero 2 W, Pi 3, Pi 4, CM4, Pi 5 and
CM5: the boot partition, and a root filesystem of musl and busybox
with the kernel modules that match the shipped kernel.

Branch	rel-2026.8.1
Commit	52056e736d87a0a5a80fe4ed8b23dfefecd74b83
Boot partition	v2026.8.0
Raspberry Pi firmware	1.20260521
Kernels	6.18.32-v8+ 6.18.32-v8-16k+

Booted to a login prompt under QEMU as a Pi Zero 2 W, a Pi 3, a Pi 4
and a CM4 before publishing.

Logging in

Log in as root with the password sepiaos. It is good for
exactly one login: the first thing the shell does is make you choose
a new one.

First boot

The image is small on purpose. On its first boot it grows the root
filesystem to fill the card, adds a swap partition (1, 2 or 4 GiB
depending on the card's size) and reboots once - so the first boot
takes a little longer than the ones after it.

Flashing

Verify the download, then write it - on Linux:

sha256sum -c SHA256SUMS
xz -d sepiaos-v2026.8.1.img.xz
sudo dd if=sepiaos-v2026.8.1.img of=/dev/sdX bs=4M conv=fsync status=progress

On macOS the device is /dev/rdiskN and the block size is spelled
bs=4m; shasum -a 256 -c SHA256SUMS replaces sha256sum.
