Gentoo requires a higher level of Linux understanding, but you will be rewarded with exactly the distribution you want and nothing more.
This is a category specific to those who want to show their prowess with the Linux operating system. This is for those who know Linux better than most and want a distribution built specifically to their needs. When this flavor of Linux is desired, there is only one release that comes to mind…Gentoo.
Gentoo is a source-based Linux distribution that starts out as a live instance and requires you to then build everything you need from source. This not only requires a higher level of Linux understanding but also demands more time and patience. In the end, however, you will be rewarded with exactly the distribution you want and nothing more. Gentoo is not new, it’s been around for quite some time; but if you want to prove your Linux skills, it helps to start with Gentoo.
