I'm not sure why osdfs is different in this regard. You need to be careful with the filesystem layout anyway -- when you upgrade the kernel, it still needs to be able to access all the files contained in existing filesystems. And it needs to create new files which are still readable by older kernels (users have this pesky habit of downgrading). -- Matthew Wilcox Intel Open Source Technology Centre "Bill, look, we understand that you're interested in selling us this operating system, but compare it to ours.
