The fact is, it's 17% better on a regular kernel tarball (not exactly a contrived test), so there would be reason to use it. It's also faster to decompress. http://tukaani.org/lzma/ This utility appears to address most of my original concerns (i.e., it works with stream LZMA and has a bzip2/gzip-esque frontend). I could see LZMA replacing bzip2, but not gzip, due to the compression performance issues. -- Cheers, Alistair.
