1.5.1. 安装器：debian-installer
debian-installer，以极度模块化设计以便尽量通用，针对前述的第一个目标。含盖极为广泛的安装环境，能够支持特殊个案的安装器。
模块化，让情况很复杂，开发者极难发掘此工具；但在图书或文本模式下，用户的经验仍然差不多。花了极大的力气减少安装所需的问题，特别感谢自动侦测硬件的软件。
值得注意的是 Debian 的衍生发行版在这个层面上有很大的不同，提供有限的安装方式 (通常只限 i386 或 amd64 架构两种)，但对初入门者更为友善。另一方面，它们通常不会让软件软件包的内容离太远，以便尽可能利用 Debian 提供的广大软件而不致于发生兼容性问题。
Quantitatively, Debian is undeniably the leader in this respect, with over 25,000 source packages. Qualitatively, Debian’s policy and long testing period prior to releasing a new stable version justify its reputation for stability and consistency. As far as availability, everything is available on-line through many mirrors worldwide, with updates pushed out every six hours.
Many retailers sell DVD-ROMs on the Internet at a very low price (often at cost), the “images” for which are freely available for download. There is only one drawback: the low frequency of releases of new stable versions (their development sometimes takes more than two years), which delays the inclusion of new software.
