Linux Weekly News

Despite its increasing popularity, the Rust programming language is still supported by a single compiler, the LLVM-based rustc. At the 2025 GNU Tools Cauldron, Pierre-Emmanuel Patry said that a lot of people are waiting for a GCC-based Rust compiler before jumping into the language. Patry, who is working on just that compiler (known as "gccrs"), provided an update on the status of that project and what is coming next.

Sudden increases in the size of Fedora's initramfs files have prompted the project to fast-track a proposal to increase the default size of the /boot partition for new installs of Fedora 43 and later. The project has also walked back a few changes that have contributed to larger initramfs files, but the ever-increasing size of firmware means that the need for more room is unavoidable. The Fedora Engineering Steering Council (FESCo) has approved a last-minute change just before the final freeze for Fedora 43 to increase the default size of the /boot partition from 1GB to 2GB; this will leave plenty of space for kernels and initramfs images if a user is installing from scratch, but it is of no help for users upgrading from Fedora 42.

Ubuntu 25.10, "Questing Quokka", has been released. This release includes Linux 6.17, GNOME 49, GCC 15, Python 3.13.7, Rust 1.85, and more. This release also features Rust-based implementations of sudo and coreutils; LWN covered the switch to the Rust-based tools in March. The 25.10 version of Ubuntu flavors Edubuntu, Kubuntu, Lubuntu, Ubuntu Budgie, Ubuntu Cinnamon, Ubuntu Kylin, Ubuntu MATE, Ubuntu Studio, and Xubuntu have also been released.

Security updates have been issued by AlmaLinux (gnutls, kernel, kernel-rt, and open-vm-tools), Debian (chromium, python-django, and redis), Fedora (chromium, insight, mirrorlist-server, oci-seccomp-bpf-hook, rust-maxminddb, rust-prometheus, rust-prometheus_exporter, rust-protobuf, rust-protobuf-codegen, rust-protobuf-parse, rust-protobuf-support, turbo-attack, and yarnpkg), Oracle (iputils, kernel, open-vm-tools, redis, and valkey), Red Hat (perl-File-Find-Rule and perl-File-Find-Rule-Perl), SUSE (expat, ImageMagick, matrix-synapse, python-xmltodict, redis, redis7, and valkey), and Ubuntu (fort-validator and imagemagick).

Inside this week's LWN.net Weekly Edition:

Firefox has long had support for multiple profiles to store personal information such as bookmarks, passwords, and user preferences. However, Firefox did not make profiles particularly discoverable or easy to manage. That is about to change; Mozilla has announced that it is launching a profile-management feature that will make it easier to create and switch between profiles. According to the support page for the feature, it will be rolled out to users gradually beginning on October 14.
