Gentoo linux
Gentoo is a free operating system based on either Linux or FreeBSD that can beautomatically optimized and customized for just about any application or need.Extreme configurability, performance and a top-notch user and developercommunity are all hallmarks of the Gentoo experience.
Thanks to a technology called Portage, Gentoo can become an idealsecure server, development workstation, professional desktop, gaming system,embedded solution or something else -- whatever you need it to be. Because ofits near-unlimited adaptability, we call Gentoo a metadistribution.
Portage is the heart of Gentoo, and performs many key functions.For one, Portage is the software distribution system for Gentoo.To get the latest software for Gentoo, you type one command: emerge--sync. This command tells Portage to update your local "Portage tree" overthe Internet. Your local Portage tree contains a complete collection of scriptsthat can be used by Portage to create and install the latest Gentoo packages.Currently, we have more than10000 packages in our Portage tree, with updates and new ones beingadded all the time.
Portage is also a package building and installation system. When youwant to install a package, you type emerge packagename, at which pointPortage automatically builds a custom version of the package to your exactspecifications, optimizing it for your hardware and ensuring that the optionalfeatures in the package that you want are enabled -- and those you don'twant aren't.
Portage has around 7,000 packages in its Portage tree, with new ones being added all the time. When you want to install a package, you type emerge packagename,and Portage automatically builds a custom version of the package toyour exact specifications, optimizing it for your hardware and ensuringthat the optional features in the package that you want are enabled --and those you don't want aren't.
