You'll get everything he listed, but ext2 has a few exotic features that tar doesn't: 1) ACLs and EAs (if you have the patches from acl.bestbits.at) 2) HURD translator and author data 3) Sparse files 4) The noatime, sync, append only, compressed, nodump, immutable, journaled, secure delete, and undeletable attributes. Very few of these are generally useful, and numbers 1 and 4 need unusual patches to use fully, but they are there for a reason, and most tars don't support them. Plus, in the future, we're likely to get multiple file forks, which really will need backing up. Burning an ext2 image onto a CD is a strange thing to do, but not without its merit.
