Synaptic package manager running on WSL. Version 2 introduces changes in the architecture. Microsoft has opted for virtualization through a highly optimized subset of Hyper-V features, in order to run the kernel and distributions (based upon the kernel), promising performance equivalent to WSL 1.
This allows drivers and devices outside of the mainline kernel to continue working after a Linux kernel upgrade. [3] Another benefit of DKMS is that it allows the installation of a new driver on an existing system, running an arbitrary kernel version, without any need for manual compilation or precompiled packages provided by the vendor.
29 August 2021 [86] 5.14.21 [87] Greg Kroah-Hartman November 2021 [87] Used in RHEL 9.x and derivatives [88] (Redhat ignores LTS-Kernel, own kernel-backports) and SLE 15 SP4/openSUSE Leap 15.4 5.13 27 June 2021 [89] 5.13.19 [90] Greg Kroah-Hartman & Sasha Levin September 2021 [90] Support for Zstd compressed modules [91]
The patch is compiled as usual, but the generated code has additional information about all changed code pieces caused by original source code modification and information on to how to apply these code pieces. The resulting code modifications are safely applied to the running kernel. A special KernelCare kernel module applies the patches. It ...
kpatch is a feature of the Linux kernel that implements live patching of a running kernel, which allows kernel patches to be applied while the kernel is still running. By avoiding the need for rebooting the system with a new kernel that contains the desired patches, kpatch aims to maximize the system uptime and availability.
Snap is a software packaging and deployment system developed by Canonical for operating systems that use the Linux kernel and the systemd init system. The packages, called snaps, and the tool for using them, snapd, work across a range of Linux distributions [3] and allow upstream software developers to distribute their applications directly to users.
Ubuntu 22.04 LTS Desktop uses Linux kernel 5.17 for newer hardware and a rolling HWE (hardware enablement) kernel based on version 5.15 for other hardware; Ubuntu 22.04 LTS Server uses version 5.15, while Ubuntu Cloud and Ubuntu for IoT use an optimized kernel based on version 5.15. It updates Python to 3.10 and Ruby to 3.0. [274]
Alpine's package management system, the Alpine Package Keeper (apk), [a] [4] was originally a collection of shell scripts [16] but was later rewritten in C. [17] The aim of this package manager is to achieve a high install and update speed, which it does by writing new data directly in-place into the operating system's file system , rather than ...
