Fans of ReactOS, an open source operating system which strives for binary compatibility with Microsoft Windows, will be happy to learn file system support for ReactOS is expanding. One of the project's Google Summer of Code (GSoC) efforts is to get ReactOS to boot from a Btrfs storage volume. Btrfs is typically only used on Linux, but ReactOS can now read and boot from Btrfs partitions. "Freeloader is now able to read files and follow symlinks from Btrfs partition. One major issue is left here - case sensitivity. Btrfs is case-sensitive file system, so paths like /ReactOS/System32, /reactos/system32, /ReactOS/system32 are different here. But in Windows world most software is written assuming that case does not matter during path lookup. This thing is solved in WinBtrfs driver, but for Freeloader it can be a bit tricky. Right now I've implemented a hack for this, we will handle this later." Details can be found in the project's blog post.
