I'll do whatever I'm told. :) Ted hasn't replied in a couple of days, but I would surmise from digging in the ext4 code that we've never exposed the huge file flag to userspace, so it'd probably be better to withdraw the documentation/code of the 'h' option from the chattr manpage instead. ext2/ext3 never had such a flag at all, so it's unlikely to break anything. --D > Tyson
