In a more general sense, I'm wary of the various efforts to get ZFS into linux. It's very unlikely to be included in the mainstream kernel in a hurry, due to licensing issues, and while some distros may offer it as a feature, it is limited in many ways (eg, with Sabayon, you can't easily install to ZFS). Further, once you've got your system onto a ZFS filesystem, you're reliant on the continued support of whoever got it there. With an in-kernel filesystem, you have far more support. It's a shame, I'd really like to be able to use some of ZFS's features, but I don't think it's ready in linux
Hello Daniel, Thank you very much for your thoughtful analysis and comments. I'll probably use your suggestion of using md5sums for sorting the file archive. What were the ZFS feature you thought you'd like to use? Cheers, Chris
