google-chrome-os - 您会提倡在 Google Chrome 操作系统中包含哪些研究操作系统功能

Question

想象一下，一家大型企业正在构建一个新的操作系统，其向后兼容性要求仅限于:

运行以 HTML5 呈现并使用 CSS3 样式的 JavaScript 编写(或编译为)现有应用程序

对打印机、外部存储和光驱的即插即用支持

与 Internet 断开连接时优雅降级

足够的进程配额以支持安全地允许任务在后台运行，包括计时器

您希望看到现有研究操作系统(例如 Plan 9 )的哪些具体功能通过此 channel 进入主流？请将您的建议限制在已实现的内容上，并提供实现的链接(或至少搜索字词)。

来自 Plan 9 docs :

Plan 9 began in the late 1980’s as an attempt to have it both ways: to build a system that was centrally administered and cost-effective using cheap modern microcomputers as its computing elements.

上网本有资格作为廉价的现代微型计算机，而云有资格作为集中管理。除了扩展 1970 年代的分时操作系统之外，还有机会实现我们希望上网本拥有的功能(用 DDaviesBrackett 的话)；研究操作系统可能已经通过示例证明了替代方案的值(value)。

来自 the Plan 9 FAQ :

Subject: What are its key ideas?

Plan 9 exploits, as far as possible, three basic technical ideas: first, all the system objects present themselves as named files that are manipulated by read/write operations; second, all these files may exist either locally or remotely, and respond to a standard protocol; third, the file system name space - the set of objects visible to a program - is dynamically and individually adjustable for each of the programs running on a particular machine. The first two of these ideas were foreshadowed in Unix and to a lesser extent in other systems, while the third is new: it allows a new engineering solution to the problems of distributed computing and graphics. Plan 9's approach means that application programs don't need to know where they are running; where, and on what kind of machine, to run a Plan 9 program is an economic decision that doesn't affect the construction of the application itself.

这似乎不太适合上网本/云域？

Answer 1

我会提倡 Chrome OS 的哪些操作系统功能？

这是我作为 Plan 9/Inferno 粉丝的愿望 list :

作为文件系统的资源(IP 堆栈、图形等)。

网络透明文件系统(即 9P )。

每个进程的私有(private)命名空间。

类似 Factotum 的身份验证系统(即，没有 root 用户)。

到处都是纯 UTF-8。

极其轻量级的流程。

自动快照和重复数据删除存储(ala venti+fossil)。

我猜还有很多其他人，但这足以让我很高兴。

这不是每次看到的“操作系统功能”，但我希望有一个带有鼠标和弦的 GUI。
