Gentoo

Gentoo is a source-based Linux distribution: packages are compiled from source on your own machine, with per-package build options (USE flags) controlling which features get compiled in. This trades install time for a highly customizable, minimal system. Package management is handled by Portage via the emerge command.

Check this Handbook for installation instruction.

Basic usage

# sync the package tree
emerge --sync

# install a package
emerge --ask app-editors/vim

# update the whole system (respecting new USE flags)
emerge --ask --update --deep --newuse @world

# remove a package and unused dependencies
emerge --deselect app-editors/vim
emerge --ask --depclean
