Fedora 45 is replacing GNOME Keyring with oo7 as the system-wide Secret Service provider. On my Beta Workstation VM the swap has not landed yet: gnome-keyring still owns the org.freedesktop.secrets bus. Your saved passwords migrate automatically, and the prompts you use every day stay exactly the same - only the daemon underneath changes.
Fedora 45 brings first-class Stratis support to the Anaconda WebUI installer. This guide walks through installing Fedora 45 with root and home on a Stratis pool: boot partitions, pool creation with encryption and over-provisioning options, thin-provisioned filesystems, post-install verification with stratis and findmnt, Kickstart automation, and troubleshooting the known early-boot hang.
When RAM fills up, Linux reclaims page cache, pushes anonymous pages to swap, and calls the OOM killer only as a last resort. This guide explains that whole chain in plain language, then shows you the observation commands - free, vmstat, PSI, and dmesg - to watch memory pressure build live on your machine.
Test your Linux archives and compression knowledge with this 15-question quiz covering tar flags, gzip, bzip2, xz, zstd, zip, compression ratios, and tar incremental backups. Built for sysadmins and power users at four difficulty tiers who want to pack, compress, and extract files like a pro, from tar basics to zstd multithreading.
Cache-aware scheduling arrived in Linux 7.2 as the biggest core-scheduler change since 6.6. I verified CONFIG_SCHED_CACHE and the llc_balancing debugfs tunables on a live Arch 7.2.7 kernel, mapped LLC domains in sysfs, and documented who actually benefits: multi-LLC servers running database workloads. Single-LLC desktops see nothing, and Intel hybrid fixes wait for 7.3.
Fedora 45 Beta shipped September 15 and this guide explains what Beta actually means on Fedora, how community testing gates what Final ships, and how to try F45 safely in a virtual machine instead of gambling your daily driver. Covers dnf5 system-upgrade steps, verification commands, and how to file useful feedback.
Linux is moving its text console out of the kernel. This explainer covers what kmscon is, how it differs from fbcon, why crash isolation and kernel-mode UI were a real liability, Fedora 45's default switch, how to enable kmscon on Ubuntu, Debian, and Arch, and how to revert safely to getty.
