The new implementation is currently only used in the installer, but is intended to eventually replace the original entirely. Both implementations make use of the same protocol for communication between the debconf front-end and the client code ("confmodule"); this is a simple line-based protocol similar to common Internet protocols.
On a Linux system, the boot partition (/boot) may be encrypted if the bootloader itself supports LUKS (e.g. GRUB). This is undertaken to prevent tampering with the Linux kernel. However, the first stage bootloader or an EFI system partition cannot be encrypted (see Full disk encryption#The boot key problem). [14]
Debian-Installer is a system installer for Debian and its derivatives. It originally appeared in Skolelinux (Debian-Edu) 1.0, [ 2 ] released in June 2004, but is now used as the official installation system since Debian 3.1 (Sarge), which was released on June 6, 2005.
Debian GNU/Hurd is a flavor based on the Hurd kernel (which, in turn, runs on the GNU Mach microkernel), instead of the Linux kernel. Debian GNU/Hurd has been in development since 1998, [ 252 ] and made a formal release in May 2013, with 78% of the software packaged for Debian GNU/Linux ported to the GNU Hurd. [ 253 ]
The startup function startup_32() for the kernel (also called the swapper or process 0) establishes memory management (paging tables and memory paging), detects the type of CPU and any additional functionality such as floating point capabilities, and then switches to non-architecture specific Linux kernel functionality via a call to start ...
AppArmor ("Application Armor") is a Linux kernel security module that allows the system administrator to restrict programs' capabilities with per-program profiles. Profiles can allow capabilities like network access, raw socket access, and the permission to read, write, or execute files on matching paths.
The device mapper is a framework provided by the Linux kernel for mapping physical block devices onto higher-level virtual block devices.It forms the foundation of the logical volume manager (LVM), software RAIDs and dm-crypt disk encryption, and offers additional features such as file system snapshots.
According to the Free Software Foundation Latin America, Linux-libre is a modified version of the Linux kernel that contains no binary blobs, obfuscated code, or code released under proprietary licenses. [7] In the Linux kernel, those types of code are mostly used for proprietary firmware images. While generally redistributable, they do not ...
