Yes, Debian is still a pain to install, especially when compared to some others Linux distributions such as Red Hat, Mandrake or SuSE. However, one has to admire how a group of volunteers from all over the world came together to design this tremendously solid and stable distribution. Some say it lags behind quite a bit, but sure that is not a problem for a server. Some other people say it is "too political" because it sticks to free software only, but that also removes unnecessary headaches for the system administrators.
