2.3. 为什么选择 GNU/Linux 发行版?

诸多因素导致了这一选择。熟悉此发行版的系统管理员保证它被作为此次计算机系统升级换代的备选方案之一。困难的经济条件及残酷的竞争限制了升级的预算,尽管它对公司的未来有着至关重要的影响。这就是为什么开源方案被很快地采纳:最近的研究指出它们相比较于proprietary方案来说更加便宜,其质量并不低于proprietary方案,只要有训练有素的员工去运维这些开源项目。
Among free operating systems, the IT department looked at the free BSD systems (OpenBSD, FreeBSD, and NetBSD), GNU Hurd, and Linux distributions. GNU Hurd, which has not yet released a stable version, was immediately rejected. The choice is simpler between BSD and Linux. The former have many merits, especially on servers. Pragmatism, however, led to choosing a Linux system, since its installed base and popularity are both very significant and have many positive consequences. One of these consequences is that it is easier to find qualified personnel to administer Linux machines than technicians experienced with BSD. Furthermore, Linux adapts to newer hardware faster than BSD (although they are often neck and neck in this race). Finally, Linux distributions are often more adapted to user-friendly graphical user interfaces, indispensable for beginners during migration of all office machines to a new system.
