CoreOS公司声称，CoreOS将会和这些发行版不同，它将不会有重大更新，而这些更新通常需要一次更新更新所有的包。它的更新和新特征将会在就绪后自动。。。。CoreOS will be different from these distributions, the company asserted, in that there will be no major updates, which typically require updating all the packages in the distribution at once. Instead, updates and new features will be streamed automatically to the copy of the OS and applied as soon as they are ready.
The service offers a dashboard, called CoreUpdate, that provides controls for designating which software packages should get updated, should the administrator not want all the packages to be updated automatically.
CoreUpdate can manage multiple machines at once, and offers a roll-back capability should an update cause issues.
Launched last December, CoreOS was designed to [focus][4] on an emerging use of the open-source OS kernel -- that of powering lots of cloud-based virtual servers.
The average CoreOS instance was designed to consume only less than half of what other Linux distributions typically consume. All applications that run on the distribution run in Docker virtualized containers, so they can be started almost instantaneously.
The distribution can be updated more easily [due to its novel use of two partitions][5]. One can contain the current version of the OS while the OS is being updated in the other, smoothing the process of upgrading a package, or the entire distribution.
The CoreOS service can be run on-premises, or through Amazon, Google and Rackspace cloud services.
CoreOS also announced Monday that it received $8 million in backing from the Kleiner Perkins Caulfield and Byers venture capital firm. The company has previously gotten investment from Sequoia Capital and Fuel Capital.
