Minimalism and security first repository of reproducible and multi-signed OCI images of common open source software toolchains full-source bootstrapped from Stage 0 all the way up.
Minimalism and security first repository of reproducible and multi-signed OCI
images of common open source software toolchains full-source bootstrapped from
Stage 0 to the compiler and libraries you'll use.

# **Minimalism and security first repository**
# Minimalism and security first repository
Most Linux distributions are built for **compatibility** rather than **security**
Approach the distribution of a toolchain by ensuring each component uses
exactly what it needs to build - no more, no less.
This results in a dramatic increase of attack surface area of an operating system
TODO: include image describing traditional package building, by installing
_every_ dependency in a single OS, with a comparison of stagex only having mini
Containerfiles with just what each project needs.
StageX is designed to allow the creation of application specific environments with a minimal footprint to eliminate attack surface area.
<!-- Speaker notes
Most Linux distributions are built for *compatibility* rather than *security*.
This results in a dramatic increase of attack surface area of an operating
system. StageX is designed to allow the creation of application specific
environments with a minimal footprint to eliminate attack surface area. Each
component of the toolchain installs only what it needs, and only packages what
it builds, resulting in a decreased attack surface.
