I'm not against adding cool features, but are there people who really need a root filesystem of one whole terabyte or larger? I've never needed my root filesystem to be larger than, say, a gigabyte or two. The only case for which this might make some sense is an external hard drive, formatted FFS2, on a 1T+ drive nearly full of personal files that just happens to have a bsd.rd in the root to reinstall/upgrade a hosed system. For most others, there should be a note that making your root filesystem That Big is usually a Really Bad Idea. -- Shawn K. Quinn skqu...@rushpost.com
