Enable Gentoo's buildpkg FEATURE to generate binary packages during compilation, then reuse them across identical-architecture systems to eliminate redundant builds. Includes configuration, a worked example with vim, and the critical trade-offs around USE flag consistency and disk usage.
I maintain a Gentoo system on a machine with limited RAM and CPU, and large packages like webkit-gtk and libreoffice are impractical to compile from source on every update. Portage documents two relevant paths: pulling prebuilt binary packages via FEATURES="getbinpkg" with a configured binhost , or building from source locally while passing --buildpkg so reu
Gentoo's Portage package manager supports both source compilation and binary packages (binpkgs). Source builds allow per-package USE flag and CFLAGS customization, while binpkgs reduce build time and CPU load. The trade-off becomes concrete when a system must preserve a small set of custom USE flags but also needs to shorten update windows. The unresolved de
Integration of System Profiles and Prebuilt Binaries Gentoo utilizes system profiles to define default USE flags, which dictate compile-time features for ebuilds. When deploying binary packages (prebuilts) across different environments, the target system's local USE flag configuration in /etc/portage/make.conf may diverge from the flags used during the binar
