How To Install Using Sfv Files' title='How To Install Using Sfv Files' />What We are Building. This course walks through the creation of a 6. Linux kernel. Our goal is to produce a small, sleek system well suited for hosting containers or being employed as a virtual machine. Because we dont need every piece of functionality under the sun, were not going to include every piece of software you might find in a typical distro. This distribution is intended to be minimal. Here is what our end result will look like 6. Linux 4. 8 Kernel with GCC 6. A system compatible with both EFI and BIOS hardware. Bootable with GRUB2.

This course provides step by step instructions in an effort to build the Linux kernel, the GNU C Standard Library implementation, GCC, and user land binaries from source. The tasks are presented in linear order, and must be followed sequentially, as later tasks have dependencies on early tasks. Do not skip around. Following this guide as intended will, in turn, enlighten you to many of the hows and whys of Linux, and assist in your ability to do tasks such as Troubleshooting issues with the kernel. Troubleshooting issues with user land software. Understanding the rationale behind various security systems and measures. SmartPCFixer is a fully featured and easytouse system optimization suite. With it, you can clean windows registry, remove cache files, fix errors, defrag disk. Performance tuning the kernel. Performance tuning user land binaries. Building or rolling your own distribution. Building user land binaries from source. Back to top. Required Skills and Knowledge. We make extensive use of Virtual. Box in this course. Working knowledge of Virtual. Box and a solid foundation in Linux and Linux troubleshooting are essential. If youre not as familiar with Virtual. Box as you would like, take a look at the How to Install Cent. OS 7 with Virtual. Box lesson in the Linux Essentials Certification course. That course, as well, provides the foundational knowledge required for this course. Back to top. Standards. As we progress through this course, we will adhere to the FHS Filesystem Hierarchy Standard specification, version 3. We will adhere mostly to the LSB Linux Standard Base specification, version 5. See the pertinent sections in this guide for more information on these two topics. Back to top. Filesystem Hierarchy Standard. We follow the FHS 3. The FHS provides guidance as to how the filesystem should be structured in terms of directory structure, partition location, and directory use. FHS 3. 0 specifies four major file categories Static OR variable. Shareable OR unshareable. It would seem there are two categories above however, there are not. Static and variable represent two mutually exclusive categories, as do shareable and unshareable. A file must fit into one of these four categories that is, it must be static or variable, shareable or unsharable or some combination thereof. All files fall into two of the four categories, without exception. The following directories are required in the primary or root hierarchy their use is as noted.

User home directories are located in usrhome, which is linked to home. This standard also specifies in detail which binaries are required more information regarding this may be found at. Back to top. Linux Standard Base. We follow the LSB Core Specification for the 6. LSB5. 0. 0LSB Core AMD6. LSB Core AMD6. 4book. The LSB standard is expansive, and outside of the scope of this course. Adherence and deviance from the standard will be pointed out in the course where we feel it is important to do so. Back to top. A Word on LinuxLinux as a term refers to two things First, it refers specifically to the Linux kernel. Second, in a broader sense, it refers to the various packagings of the Linux kernel with other programs to provide the functionality required of a complete operating system. Sound strange Its not its one of the things that makes Linux so versatile. The kernel itself manages the hardware, memory, and the other parts of a computer system which are typically opaque to installed programs. Programs installed to provide additional functionality are referred to as user land or the user land. The combination of kernel and user land constitute what are referred to as distributions, many of which we are familiar Red Hat Enterprise Linux, Ubuntu, Arch, Fedora, and so on. Installing A New Version Of Microsoft Office. In a broad sense, the term Linux refers to the operating systems created by the pairing of kernel and user land, but the term is ambiguous. Distribution, on the other hand, refers to the pairing of the kernel with a user land built to some specification. Ubuntu, for instance, varies quite a bit from Cent. OS 6. Both of these are separate distributions of Linux. Unlike operating systems, which are built in a monolithic fashion where the user land and kernel are tightly coupled, such as Free. BSD, VMS, Windows, etc., Linux allows for variations on theme which number into the thousands. The term distro better fits these variations, as each one is not entirely unique from the next because of the shared kernel but may differ substantially in terms of the user land. Back to top. Section 2. Prerequisites Build System Specifications. KernelDistro Version. We use Fedora Core 2. You can run any distribution which uses a 4. Some distributions may package utilities using older or incompatible versions than what ia needed in this course. Clean Install. We strongly recommend that you use a clean install for the build system. Notice we undertake the whole of this course in a virtual machine running in Virtual. Box we do this to facilitate the building of Linux in a clean environment. Any virtualization environment will do, provided you have access to the console, as it may be necessary at various points. Actual hardware is also acceptable, if those resources are readily available to you. Build System Disk Partitions. The build system the virtual machine we use to build Linux uses the following disk layout. This output is from the parted print all command Number Start End Size Type File system Flags. B 5. 25.

Whilst we walk through the creation of the destination drive where our newly built distribution will be installed in the videos, you should have the proficiency to install Linux and the necessary tools prior to undertaking this course. It is strongly recommended that you take the Linux Essentials course on Linux.
