It's in mainline so I don't know why it would not be built. It certainly
exists on Fedora. You could get Fedora live image, dd to a USB stick and it
will boot the Mac.

The much bigger problem is recent OS X versions default to, and convert on
updating prior versions to, Core Storage volumes. This is Apple's
equivalent of LVM. And there is no open source code for this. Upstream
liblkid doesn't even recognize it. It's actually a big problem as it
renders OS X HFS unreadable outside of OS X.

Microsoft's equivalent is Storage Spaces. But as yet it's not used by
default. Likewise no support on Linux still.
