KERNEL RC8 LOCKS DOWN NAMESPACE MOUNTS, RISC-V AND POWER FIXES LAND

The kernel is tightening namespace security while Arch's installer learns to handle missing keyrings and Wayland compositor startup.

Linux 7.1-rc8 is closing a namespace security hole that let attackers mount regular files over directories through OPEN_TREE_NAMESPACE and FSMOUNT_NAMESPACE, bypassing normal mount restrictions [1]. Simultaneously, power management fixes restore EPP control in amd-pstate [2] and RISC-V closes a CFI prctl implementation gap that was silently accepting invalid control bits [3]. Over in Arch's installer, three critical fixes landed overnight: custom mirrors now skip configuration if keyring sync fails rather than crashing with GPGME errors [4], Wayland desktop profiles now automatically add users to the seat group so sway and hyprland actually start [5], and Plymouth boot splash support arrived as an opt-in feature [6]. The namespace fix is kernel-critical for production systems. The Arch fixes matter heavily if you're shipping Wayland-first installs or running in environments where keyring sync is flaky.
