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."
