Bedrock Linux is a Linux distribution created with the aim of making most of the (often seemingly mutually-exclusive) benefits of various other Linux distributions available simultaneously and transparently.
If one would like a rock-solid stable base (for example, from Debian or a RHEL clone) yet still have easy access to cutting-edge packages (from, say, Arch Linux), automate compiling packages with Gentoo's portage, and ensure that software aimed only for the ever popular Ubuntu will run smoothly - all at the same time, in the same distribution - Bedrock Linux will provide a means to achieve this.
