An experimental "Pre-RC3" image for the Aeon Desktop has been published and testers are encouraged to try out the final prototype before it becomes the official Release Candidate 3 (RC3). The new image can be downloaded from the openSUSE development repository.

This prototype, which has been submitted to openSUSE Factory, introduces some significant changes and improvements. Notably, the dd backend in the tik installer has been replaced with a new systemd-repart backend. This change allows for the installation of Aeon with Full Disk Encryption that enhances the security features of the operating system.

Existing users of Aeon RC2 and earlier versions will need to perform a reinstall to take advantage of the new features destined for RC3. Due to the fundamental changes in partition layout necessary for the new encryption features, an in-place upgrade from RC2 is not feasible without risking data integrity, according to a post on the new Aeon Desktop subreddit. Users can utilize Aeon's reinstall feature, which facilitates the backup and restoration of user data as long as a sufficiently large USB stick is used.

Users installing the prototype image may encounter some packages from the OBS devel project. These can be removed by running transactional-update --interactive dup and selecting solutions that replace devel:microos packages with official ones.

Testers are encouraged to provide feedback and report any issues encountered during the testing phase on the Aeon Desktop bug report page.

Next Steps

If the prototype is accepted into Factory and becomes RC3, the development of Aeon will be in its final stages before an official release. RC3 will serve as the basis for writing openQA tests for Aeon, which are crucial for ensuring the desktop's stability and functionality.

There is a possibility of an RC4, which aims to streamline the installer process by embedding the full Aeon install within the installer image, potentially reducing the download size by 50 percent. If this approach is not feasible in the short term, it may be revisited post-release.

Full Disk Encryption is set up in one of two modes: Default or Fallback. Get more info about that in the Aeon Desktop Introduces Comprehensive Full Disk Encryption article.

"We worked very closely with Capcom, and our relationship definitely grew in the process"

Full Disk Encryption is planned to be introduced in the forthcoming release candidate of the Aeon Desktop to enhance data security for its users.
The feature is expected to be included in the upcoming Release Candidate 3 (RC3).

Full Disk Encryption is designed to protect data in cases of device loss, theft or unauthorized booting into an alternative operating system.
Depending on the hardware configuration of a system, Aeon's encryption will be set up in one of two modes: Default or Fallback.

Default Mode

The Default Mode is the preferred method of encryption provided the system has the required hardware. This mode utilizes the Trusted Platform Module(TPM) 2.0 chipset with PolicyAuthorizeNV support (TPM 2.0 version 1.38 or newer). In this mode, Aeon Desktop measures several aspects of the system's integrity. These including:

• UEFI Firmware
• Secure Boot state (enabled or disabled)
• Partition Table
• Boot loader and drivers
• Kernel and initrd (including kernel command line parameters)

These measurements are stored in the system's TPM. During startup, the current state is compared with the stored measurements. If these match, the system boots normally. If discrepancies are found, users are prompted to enter a Recovery Key provided during installation. This safeguard ensures that unauthorized changes or tampering attempts are flagged.

Fallback Mode

The Fallback Mode is employed when the necessary hardware for Default Mode is not detected. This mode requires users to enter a passphrase each time the system starts. While it does not check system integrity as comprehensively as Default Mode, Secure Boot is strongly recommended to ensure some level of security, confirming that the bootloader and kernel have not been tampered with.

Contrary to initial concerns, Default Mode is not less secure than Fallback Mode despite not requiring a passphrase at startup. The strong integrity checks in Default Mode protect against attacks that could bypass normal authentication methods. For example, it can detect changes to the kernel command line that could otherwise allow unauthorized access. Furthermore, it safeguards against modifications to initrd thereby preventing potential passphrase capture in Fallback Mode.

Secure Boot, while optional in Default Mode due to the comprehensive integrity checks, is critical in Fallback Mode to maintain system security. Disabling Secure Boot in Fallback Mode increases vulnerability to tampering and attacks aimed at capturing the passphrase.

Aeon's implementation of Full Disk Encryption provides robust security options tailored to the capabilities of users' hardware. By offering both Default and Fallback modes, Aeon ensures that all users can benefit from enhanced data protection.

The inclusion of this feature in RC3 marks a significant step forward in safeguarding user data against potential threats.
Aeon users are encouraged to read and bookmark the Aeon Encryption Guide.

• Mesa and Mesa-drivers 24.1.2: Both packages underwent a specfile cleanup, involving the relocation of Rust crate sources into subprojects folders and updates to baselibs.conf. Due to the maintenance burden associated with Rust crates as system dependencies, these crates are now downloaded as vendored dependencies, as detailed in the README-suse-maintenance.md. The update adds support for building libvulkan_nouveau, including necessary Rust crates such as paste-1.0.14, proc-macro2-1.0.70, quote-1.0.33, syn-2.0.39, and unicode-ident-1.0.12. However, building libvulkan_nouveau on Leap is not possible due to the requirement for rust-cbindgen >= 0.25. For more details, refer to the release notes at https://docs.mesa3d.org/relnotes/24.1.2.
• KDE Plasma 6.1.1: Discover improves UI elements and Packagekit support, while Dr Konqi corrects the Sentry dbus interface usage. Plasma Addons addresses reference issues in Effects/cube, and krdp ensures version compatibility and resolves session controller bugs. Kscreenlocker improves greeter functionality, and KWin introduces multiple fixes for shaders, tiling, and input panels. Libkscreen and libplasma update protocol versions and fix plugin loading issues. Plasma Desktop enhances task icon sizing, panel opacity and file dragging across screens. Plasma Audio Volume Control removes unnecessary symlinks, and Plasma Systemmonitor correctly positions loading overlays. Powerdevil improves battery protection UI and limits backlighthelper calls.
• Python-setuptools 70.0: Key features in this new major version include emitting warnings for ignored [tools.setuptools] entries in pyproject.toml, improved error messaging for pkg_resources.EntryPoint.require and handling None location distributions more gracefully. The update also refreshes unpinned vendored dependencies, supports PEP 625 by standardizing package name and version in filenames and ensures encoding consistency for .pth files. Obsolete Python < 3.8 code has been removed, and pkg_resources now uses stdlib importlib.machinery. Bug fixes address race conditions in the install command, improve handling of nested namespaces with package_dir and correct various pkg_resources method behaviors. The patch for reproducibility has also been refreshed.
• Xen 4.18.2_06: This version resolves intermittent system hangs when Power Control Mode is set to Minimum Power. Patches also improve CPU mask handling and interrupt movement in various scenarios. Upstream bug fixes include improvements in scheduler resource data management and include fixes for building with GNU Compiler Collection 14.

Key Package Updates

• NetworkManager 1.48.2: This package updates support for matching OVS system interfaces by MAC address and fixes port reactivation and VPN secrets handling for 2-factor authentication. It saves connection timestamps during shutdown for proper autoactivation after restart. Key changes in 1.48.0 deprecate autotools building, add support for changing OpenSSL ciphers for 802.1X authentication, and set unmanaged device reasons in the StateReason property visible in nmcli. Additionally, it replaces the mac-address-blacklist property with mac-address-denylist, improves WiFi 6 GHz band detection and optimizes performance to avoid high CPU usage during route updates. Previous version 1.46 adds brought dynamic SSID-based stable IDs, randomized MAC addresses and several enhancements for handling IPv6, D-Bus and cloud setup.
• ibus-table 1.17.6: This update drops Python2 support, transitioning all scripts to Python3 using pyupgrade. It now allows the use of keys with Unicode keysyms in keybindings, enhancing customization and flexibility. Additionally, the frames_per_buffer=chunk_size option is now utilized in self._paudio.open() for improved audio handling. The update also includes translation enhancements from Weblate, with Czech translations reaching 36.6 percent, Japanese at 45.3 percent, and Chinese (Simplified) at 92.0 percent.
• btrfsprogs 6.9: The mkfs utility now halts if the mount status cannot be determined when using the --force option and corrects the minimum size calculation for zoned devices. The check command removes the --clear-ino-cache option, shifting its functionality to the rescue command group, and adds detection and repair for incorrect file extent item ram_bytes values. The qgroup commands now sync the filesystem before searching for stale entries, handle uncleaned subvolumes and squota enabled scenarios, and display the cleaning status of subvolumes. The receive command fixes stream parsing for strict alignment hosts, and tune change-csum and dump-tree commands include updates for handling dev-replace status items. The convert command improves extent iteration for preallocated/unwritten extents. The build process now ensures compatibility with e2fsprogs 1.47.1 and improves header file dependency tracking. Documentation was also updated.
