Comment Less static hardware. (Score 4, Informative) 993
UNIX, and Linux, were designed with the concept that the hardware configuration was static during operation. So "startup" and "configuration" occured at the same time. Now that many peripherals hot-plug, that model is obsolete. Many people find it painful to switch to an "everything is dynamic" model, especially since, for many server applications, there is no hot-plugging.
Hence the unhappiness with a redesign.
This is a more general problem with UNIX/Linux. Many programs are designed on the assumption that they read a static configuration file in text format, and will be restarted if the configuration changes. Various hacks have been added to some programs to allow dynamic reconfiguration (often involving sending a signal to the process to tell it to re-read a text file). Real dynamic configuration models usually involve storing the configuration in a database, which a lot of UNIX/Linux types don't like.
