SubjectRE: OFFTOPIC: Re: bzip2 for kernel dists?
It does compress slowly, but decompression is pretty snappy (though still
slower than gzip). I think bzip2 is ideal for distributing software -
remember that decompression is going to happen a lot more times than
compression. The succession of LZ77-based compression by BWT-based
compression is inevitable as machines get faster. But it will take some
time to replace a standard as strongly entrenched as gzip. gzip is an
absolutely superb LZ77-based compressor - maybe even the best of its kind.

How about integrating the BWT-based compression in bzip2 into gzip in
order to speed the transition and make it easier?

gzip -bwt? Just an idea.
