BeleniX is essentially a first class OpenSolaris operating environment with very little modifications to the base. It is also very stable and very compatible with SUN’s OpenSolaris having derived packages out of sources from JDS, SFW, FOX, G11N, Caiman and other repos plus its own repo. It is also a full-blown OpenSolaris development environment being completely self-hosting. Every package delivered for BeleniX is built on BeleniX including the base OS (ON).
