That's an interesting point. All my btrfs are on ssd ATM and I'm still using reiserfs on the spinning rust until btrfs further stabilizes, but at some point I imagine I'll switch everything to btrfs, and I hadn't thought about this. Tho I could do with a good explanation of how both ssd and rotational superblock update handling works and the differences between the two, as I'm not entirely clear on it myself, at this point. -- Duncan - List replies preferred.
