Linux lite single user mode9/23/2023 ![]() Examples of microkernels are symbian, minix, GNU. But it has a clear advantage over monolithic architecture in terms of speed. However, in case of an error in monolithic systems, the whole system will be affected because the services are interconnected. In this respect, we can describe this architecture as durable. In Microkernel, a fault in a component does not affect the whole system thanks to the system architecture. Such cores are customizable and easily expandable. ![]() Applications also have their own address space. System services such as the file system, virtual memory manager, and CPU scheduler are in the "user mode" area on the kernel, and each has its own address space. In systems using microkernel, "kernel mode" takes up less space. However, a change to the kernel requires recompilation and the kernel code can become quite complex. It also provides high speed as there will be no message traffic. This creates a layer of security between the kernel and applications. Processes can request service from the kernel. Kernel and OS services are in the same address space. Each process is in separate address spaces. Essentially, operating systems using Monolithic kernels run all operating system functions in "kernel mode", that is, kernel space. Monolithic kernels occupy a larger area than microkernels. Especially Debian and Debian-based distributions, RHEL and RHEL-based distributions are frequently used as server operating systems. For example, Android, Debian, RHEL(Red Hat Enterprise Linux), CentOS are examples of GNU/Linux distributions. Named in 1991, this monolithic kernel is widely used in operating systems used by supercomputers, personal or mobile devices. Linus Torvalds also owns the git project, a source code management and version control software. The kernel is designed by Linus Torvalds and is still developing it as open source. Linux is an operating system kernel with a Unix-like design. Next, I'll review the bedrock Linux hierarchy and simply explain how to install and use it. ![]() In order to understand this architecture, I will first talk about the linux system hierarchy. This is a system that allows to use multiple different software packages together with a very useful and customizable architecture. Although it is described as a separate Linux distribution, we can say that it is a daemon that connects the distributions installed to the root directory and then installed in layers, to the root directory. Hello, in this article, I will talk about Bedrock Linux, which is a daemon that allows to use software packages from more than one package manager, while also installing and using multiple distributions in layers. ![]()
