Well, world is not that simple, I think:) Some algorithms are faster at decompressing, some compress better, so use less resources to decompress, etc. FreeBSD provides tools, not policies, right? Let's the administrator choose which algorithm fits best his needs. As for the code size, it should be trivial to decide which algorithms we want to compile in. --=20 Pawel Jakub Dawidek http://www.wheelsystems.com pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
