Lots of sources already use bzip2 internally, so there's a no-gain situation with some. > > We have new things in the upcoming dpkg, one of those being to support > > bzip2 in the package format.

Why? 15% b/w isn't that big of a deal unless you are mirroing the entire distribution. If that's a big deal to you in that situation, buy a CD. On top of that we start to have backward compability issues (some packages will never be able to be compressed with bzip2 to insure we can still do upgrades, etc...). Theoretically, it may sound nice, but technically, there is no gain. If we support it with the package manager, then it's a very simple script to convert all packages to bz2 internally, and CD vendors can opt to do this, and sell "compact" ISO's. -- -----------=======-=-======-=========-----------=====------------=-=------ / Ben Collins -- ...on that fantastic voyage... -- Debian GNU/Linux \ ` [EMAIL PROTECTED] -- [EMAIL PROTECTED] -- [EMAIL PROTECTED] ' `---=========------=======-------------=-=-----=-===-======-------=--=---' -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
