Geez. Then it would have taken even longer. Sometimes you have deadlines, and waiting a few hours longer is just not an option. (In this case I finally decided to not even gzip the stuff, because it saved only a few percent of space.) But this is getting off-topic. I think everyone is entitled to his own opinion about the usefulness of bzip2. But I have yet to hear a good reason why it should replace gzip in the base system of FreeBSD. Not that my opinion matters, though. :-) Using bzip2 for the FreeBSD distribution sets would increase the minimum memory requirement by 4 Mbyte (or about 2.5 Mbyte using the -s option of bunzip2, but which doubles decompression time).
