That's not correct. It won't rw mount journaled HFS+ volumes, they are mounted ro by default. You can force them to mount rw and it'll ignore the journal possibly at the immediate or near future peril of the filesystem, depending on what state its in. I don't know why linux is so far behind on supporting it and doesn't bode well for supporting Core Storage volumes. Near as I can tell while HFS+/X are part of Darwin and thus at least sorta open sourced, I'm not finding any of the Core Storage stuff open sourced meaning it'd have to be completely reverse engineered.
