v2.57.9

The boot layer 2.57.9 for FiiO's firmware 2.57 (build 8eb15a9).

Accepted on the emulator's guest: no new image: build 8eb15a9 and image 9e6448dd as release 2.57.7's, whose guest and player acceptance stands (the menu's sources left the build id, which stays 8eb15a9). On the emulator's guest at f1d5e33 with FiiO 2.57, 2026-10-11: this disc-menu and disc-network, network_guest.py 6 of 6 (a network forgotten from the menu's Wi-Fi networks screen with the emulator's buttons, another kept one in its place) and menu_guest.py 7 of 7; disc-health 2.57.7's binary byte for byte; the installer's archive unpacked outside the repository with an empty home, install.py --guest: the image built on the computer (9e6448dd), the archive's own packages (this menu, disc-server 2.57.8 as the controller, disc-health, disc-network) installed by Play, the menu answered, the controller and the services confirmed; install.py --packages --dry-run staged them. The installer's player path (one entry, the first start's check before any question) and the restart payload's bounded wait: the conformance suite (499) and restart_test with a standing Count, not yet on a player.

The image is built on your computer from FiiO's update by install.py; it is never a release file.

To install: unpack disc-installer-2.57.9.tar.gz and run python3 install.py in its folder (Python 3.11 or later, libusb, squashfs-tools 4.6 or later and openssl; the installer names any that is missing). It holds this release's files and the default server and apps; it downloads only the pinned files of diskOS (the writer and its SPL) and of the emulator (the reader of FiiO's update), each checked by its digest.
