Software remastering is software development that recreates system software and applications while incorporating customizations, with the intent that it is copied and run elsewhere for "off-label" usage. If the remastered codebase does not continue to parallel an ongoing, upstream software development, then it is a fork, not a remastered version. The term comes from ''remastering'' in media production, where it is similarly distinguished from mere copying. Remastering was popularized by Klaus Knopper, creator of Knoppix. The Free Software Foundation promotes the universal freedom to recreate and distribute computer software, for example by funding projects like the GNU Project. Remastered Linux, BSD and OpenSolaris operating system distributions are common because they are not copy protected, but also because of the allowance of such operating systems to grow an application for taking a ''snapshot'' of itself, and of installing that onto bootable media such as a thumb drive or a virtual machine in a hypervisor. Since 2001 over 1000 computer operating systems have arisen for download from the Internet.〔 To verify the numbers choose a weekly report and search for "database summary" in it.〕 A global community of GNU/Linux providers pushes the practice of remastering by developer switching, project overtaking or merging, and by sharing over the Internet.〔(【引用サイトリンク】title=GNU/Linux Distribution Timeline 12.10 )〕 Most distributions start as a remastered version of another distribution as evidenced by the announcements made at DistroWatch(). Notably, remastering SLS Linux forked Slackware, remastering Red Hat Linux helped fork Yellow Dog Linux and Mandriva and TurboLinux, and by remastering a Debian distribution, Ubuntu was started, which is itself remastered by the Linux Mint team.〔Search http://futurist.se/gldt/ to verify a lineage.〕 These might involve critical system software, but the extent of the customizations made in remastering can be as trivial as a change in a default setting of the distribution and subsequent provision to an acquaintance on installation media. When a remastered version becomes ''public'' it becomes a ''distribution''. Microsoft Windows has also been modified and remastered. Various utilities exist that combine Windows updates and device drivers with the original Windows CD/DVD installation media, a process known as slipstreaming. When remastering a distro, remastering software can be applied from the "inside" of a live operating system to clone itself into an installation package. Remastering does not necessarily require the remastering software, which only facilitates the process. For example, an application is remastered just by acquiring, modifying and recompiling its original source code. Many video games have been modded by upgrading them with additional content, levels, or game features. Notably Counter-Strike was remastered from Half-Life and went on to be marketed as a commercial product. == Introduction == Software remastering creates an application by rebuilding its code base from the software objects on an existing master repository. If the "mastering" process assembles a distribution for the release of a version, the remaster process does the same but with subtraction, modification, or addition to the master repository. Similarly a modified makefile orchestrates a computerized version of an application. When an amount of unneeded code is "cut down" to some wanted minimum it removes unwanted features that the original publisher and maintainer needs. When new features are added it evolves the software. A remastered version may consider that a feature of the original is a bug, and provides a modified copy of the feature that works in a better way. When it is published a software remaster maintains the integrity of the named product from which it was derived by adherence to a shared software repository with any modifications, and with the intention of maintaining the good name needing approval. If approval does not happen, the name and the repository have the option to become their own master. The creator of a published software remaster, if they do no further work to evolve the software, must at least arrange for maintenance support channels, such as updating user documentation, providing a forum, an internet relay chat line, or a wiki, providing intent to maintain a version for the life of its usefulness. Remastering centers around the reputation of a product, and so the distribution process requires an official, sanctioned version. This differs from the attitude in much free software in the many cases where the name of the product is "cheap" because plentiful and stable, where no guarantees or liabilities are offered, and where permission is inherently granted to redistribution any modified version under any name. The original repository is the master, from which creative flavors and spins may already be offered by the original producers. A remaster production supports any additional software from outside it, supports the new mixture of software from the original repository, or keeps the modifications of original masters on the outside the master repository. Software remastering is ''tolerated'' by the maintainers of the master repository, while free software modifications are ''encouraged'' by the same social conventions. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Software remastering」の詳細全文を読む スポンサード リンク
