A boot image control strategy is a common way to reduce total cost of ownership in organizations with large numbers of similar computers being used by users with common needs, e.g. a large corporation or government agency. This is considered part of enterprise application integration in larger shops that use that term since applications are part of the boot image, and modify the boot image, in most desktop OS. Windows Vista includes tools for boot image control, displacing third party tools. Mac OS has always had more flexible handling of boot drives, simplifying control and reducing the need to move boot images around between drives. Increasingly, boot image control is a network operating system function. == Economics == Very often a large computer vendor is required to explain in a bid in response to an RFP how they intend to simplify the purchaser's boot image control problems and the attendant service costs: The total cost of ownership correlates strongly to the total number of different images, not the total number of computers, so this is a major cost concern. Three basic strategies are commonly advised: *a single base boot image for each type of computer in the organization, customized by each user with no central control *a thin client strategy where the smallest possible boot image is used, typically one that does not include a full operating system *a departmental boot image strategy where a base boot image is customized with applications to fit each group of users, but, the users do not have the ability to upgrade or alter the configurations 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「boot image control」の詳細全文を読む スポンサード リンク
