Exherbo, a Linux distribution, based on Gentoo.
It's worth noting that Exherbo is not a user-targeted distribution at the moment. Instead, it caters to the interests and needs of its developers and contributors. Therefore, it may not support your favorite desktop environment or applications yet. However, the team is working on expanding its package offerings.
So, why did the Exherbo developers create this distribution? They wanted to do something that could suit their needs better than Gentoo. They tried and failed to achieve that goal within Gentoo's infrastructure. They found some issues with Gentoo's Portage code, management, and QA practices. Furthermore, they believed that Gentoo's focus on community over technical goals wasn't useful anymore. They also faced challenges with Gentoo's development direction and policies, which allowed many subprojects without proper discussions.
Therefore, the Exherbo team wanted to create a streamlined and focused environment that could deliver specific solutions instead of trying to do everything at once. They believe that Gentoo provided a good starting point, but a new generation of tools and development is necessary to meet their goals.
