SkyOS SkyOS has gotten a new virtual filesystem, dubbed BranchFS. This makes it possible to branch filesystems, convert read-only media into read-write media, and add SkyFS attributes to non-SkyFS volumes. "BranchFS makes it possible to make a reversible filesystem. By using your system partition you can revert to a previous state (with just one reboot) and and when using a CD BranchFS makes it possible to make changes to the content. BranchFS is still in heavy development but branching a LiveCD works quite well already. The first SkyOS LiveCD will be based on BranchFS."

Innovation?

This is not an innovation. "Branching", more usally called "union mount", is a well known concept. Using it to implement LiveCD is a commonplace. Actually, union mount was available in the system as old as 4.4 BSD!

See http://www.am-utils.org/project-unionfs.html for an implementation of this idea for Linux. Its homepage lists 30 Linux LiveCD projects already using it.

That's first thing I thought of.

It's slightly annoying that Robert renames an existing technology.

I don't think Robert ever claimed to have "invented" this idea...

Additionally, it's just a name, a way for us to refer to this technology as it is presented in SkyOS. There are thousands of different processes and sub-systems in SkyOS, and naming them something unique is a good way of keeping them straight.
