(February 2016) Installation (or setup) of a (including and ), is the act of making the program ready for. Because the process varies for each program and each computer, programs (including ) often come with an installer, a specialized program responsible for doing whatever is needed for their installation. Installation may be part of a larger process. Installation typically involves code being copied/generated from the installation files to new files on the local computer for easier access by the operating system.
Because code is generally copied/generated in multiple locations, uninstallation usually involves more than just erasing the program folder. For example, registry files and other system code may need to be modified or deleted for a complete uninstallation.
Contents. Overview Some computer programs can be executed by simply copying them into a stored on a computer and executing them. Other programs are supplied in a form unsuitable for immediate execution and therefore need an installation procedure.
Once installed, the program can be executed again and again, without the need to reinstall before each execution. Common operations performed during software installations include:. Making sure that necessary are met. Checking for existing versions of the software.
Creating or updating program and folders. Adding configuration data such as, entries or. Making the software accessible to the user, for instance by creating or.
Configuring components that run automatically, such as or. Performing. Updating the software versions These operations may require some charges or be free of charge.
In case of payment, installation costs means the costs connected and relevant to or incurred as a result of installing the drivers or the equipment in the customers' premises. Some installers may attempt to trick users into installing such as various forms of, or software of partnering companies. To prevent this, extra caution on what exactly is being asked to be installed is needed. The installation of additional software then can simply be skipped or unchecked (this may require the user to use the 'custom', 'detailed' or 'expert' version of the installation procedure). Such malicious conduct is not necessarily a decision by the software developers or their company but can also be an issue of external installers such as the installer. Necessity As mentioned earlier, some computer programs need no installation.
This was once usual for many programs which run on, and. As computing environments grew more complex and fixed replaced, the need for tangible installation presented itself. A class of modern applications that do not need installation are known as, as they may be roamed around onto different computers and run. Similarly, there are live operating systems, which do not need installation and can be run directly from a, or loaded over the network as with.
Examples are 4.0, various, or Mac OS versions 1.0 through 9.0. (See and.) Finally, which run inside a, do not need installation. Types Attended installation On systems, this is the most common form of installation. An installation process usually needs a user who attends it to make choices, such as accepting or declining an (EULA), specifying preferences such as the installation location, supplying passwords or assisting in.
In graphical environments, installers that offer a are common. Attended installers may ask users to help mitigate the errors. For instance, if the disk in which the computer program is being installed was full, the installer may ask the user to specify another target path or clear enough space in the disk. Silent installation Installation that does not display messages or windows during its progress.
'Silent installation' is not the same as 'unattended installation' (see below): All silent installations are unattended but not all unattended installations are silent. The reason behind a silent installation may be convenience or subterfuge. Is almost always installed silently. Unattended installation Installation that is performed without user interaction during its progress or with no user present at all. One of the reasons to use this approach is to automate the installation of a large number of systems. An unattended installation either does not require the user to supply anything or has received all necessary input prior to the start of installation.
Such input may be in the form of or an answer file, a file that contains all the necessary parameters. And are examples of operating systems that can be installed with an answer file.
In unattended installation, it is assumed that there is no user to help mitigate errors. For instance, if the installation medium was faulty, the installer should fail the installation, as there is no user to fix the fault or replace the medium. Unattended installers may record errors in a for later review. Headless installation Installation performed without using a connected. In attended forms of headless installation, another machine connects to the target machine (for instance, via a ) and takes over the display output. Since a headless installation does not need a user at the location of the target computer, unattended headless installers may be used to install a program on multiple machines at the same time.
Scheduled or automated installation An installation process that runs on a preset time or when a predefined condition transpires, as opposed to an installation process that starts explicitly on a user's command. For instance, a willing to install a later version of a computer program that is being used can schedule that installation to occur when that program is not running. An operating system may automatically install a device driver for a device that the user connects. (See.) Malware may also be installed automatically. For example, the infamous was installed when the user plugged an infected device to their computer.
Clean installation A clean installation is one that is done in the absence of any interfering elements such as old versions of the computer program being installed or leftovers from a previous installation. In particular, the clean installation of an operating system is an installation in which the target is erased before installation. Since the interfering elements are absent, a clean installation may succeed where an unclean installation may fail or may take significantly longer. Network installation. Not to be confused with. Network installation, shortened netinstall, is an installation of a program from a that may be done by installing a minimal system before proceeding to download further packages over the network. This may simply be a copy of the original media but software publishers which offer site licenses for institutional customers may provide a version intended for installation over a network.
Installer Look up in Wiktionary, the free dictionary. An installation program or installer is a computer program that installs files, such as applications, drivers, or other software, onto a computer. Some installers are specifically made to install the files they contain; other installers are general-purpose and work by reading the contents of the to be installed. The differences between a and an installer are. This box:. Criterion Package manager Installer Shipped with Usually, the operating system Each computer program Location of installation information One central installation database It is entirely at the discretion of the installer. It could be a file within the app's folder, or among the operating system's files and folders.
At best, they may register themselves with an uninstallers list without exposing installation information. Scope of maintenance Potentially all packages on the system Only the product with which it was bundled Developed by One package manager vendor Multiple installer vendors Package format There could be as many formats as the number of apps Package format compatibility Can be consumed as long as the package manager supports it. Either newer versions of the package manager keep supporting it or the user does not upgrade the package manager. The installer is always compatible with its, if it uses any.
How To Download Bootstrap
However, installers, like all computer programs, may be affected. Bootstrapper During the installation of computer programs it is sometimes necessary to update the installer or package manager itself.
To make this possible, a technique called is used. The common pattern for this is to use small executable files which update the installer and starts the real installation after the update.

Examples include ( and. Installation authoring tools that do not rely on Windows Installer include , (MindVision Software), (SamLogic), and. MacOS includes, a native. MacOS also includes a separate software updating application, but only supports Apple and system software.
Included in the dock as of 10.6.6, the shares many attributes with the successful for iOS devices, such as a similar app approval process, the use of Apple ID for purchases, and automatic installation and updating. Although this is Apple's preferred delivery method for macOS, previously purchased licenses can not be transferred to the Mac App Store for downloading or automatic updating. Commercial applications for macOS may also use a third-party installer, such as Mac version of (MindVision Software) or InstallerMaker. System installer A system installer is the software that is used to set up and install an operating system onto a device. Examples of system installers on Linux are and for, for and, for -based versions of, and for -based projects. Another example is found in the operating system, which uses a utility called to install itself onto a device after booting from a.

Bootstrap Setup
Cp /var/cfengine/inputs/failsafe.cf /var/cfengine/masterfiles/ We'll edit that copy in masterfiles in the next step. All files promises must never connect to an untrusted server, which means that the following line should not be found anywhere: trustkey = 'true' All occurrences of trustkey in masterfiles directory should be changed to 'false', or be removed (since it defaults to false anyway). It is certain that failsafe.cf that we copied in the previous step will contain such occurrences that should be changed. (Those occurrences are the reason that automatic bootstrapping requires a trusted network). The previous changes in masterfiles need to be properly propagated to the inputs directory.
The automated way to do that is to run the update.cf policy.
