Aether Philosophy

AetherOS is the formal name of the flagship FreeBSD-based operating system. Inside the OS and in compact contexts, the short form Aether is used.

Aether is developed directly from FreeBSD and owns the reusable FreeBSD platform capabilities that can serve both desktop systems and the separate Void mobile project.

Role

Aether is the flagship platform rather than another Linux variant.

Its responsibilities include:

• FreeBSD image composition and release policy
• native package and update integration
• Aether identity and common services
• reusable security and isolation primitives
• Linux compatibility
• development and virtualization infrastructure required to build and test the platform

Mobile-only hardware and UX remain responsibilities of Void.

Upstream contract

Aether is built from plain FreeBSD rather than another FreeBSD derivative.

It keeps FreeBSD’s native package ecosystem. pkg remains the normal binary package manager, with ports/source integration used only where explicitly required.

Exact FreeBSD release and architecture targets belong in project configuration rather than being hard-coded on this page.

Linux compatibility direction

Aether’s accepted architecture includes two Linux compatibility paths:

1. a Linux ABI compatibility path for applications that do not require a separate Linux kernel;
2. a managed Linux VM path for applications that require real Linux kernel behavior.

These are architectural commitments, not a claim that seamless integration is already complete.

Relationship to Void

Void tracks Aether as its base platform. Reusable FreeBSD capabilities belong in Aether; phone- and tablet-specific hardware, shell, telephony, sensors, app lifecycle, and mobile UX belong in Void.

Theme identity

Inside the OS, the short form Aether is used for identity and themes. The supported appearance names are Aether Light and Aether Dark.
