I think that the proper balance is to set up things in a posixish way.

FSSTND is the Linux filesystem layout standard. It defines which directory
should contain which classes of files. If we are dealing with packages
having complex dependencies on each other (which is happens just with any
package which is a bit bigish), it is very important to know which file is
where. It makes life (and especially porting) a lot easier.
As a user you might noticed the main difference between win* and operating
systems: the applications can and do depend on tools which handle
subproblems, and often considered part of the operating system. This
philosophical difference is which makes a WYSIWYG editor in 164 lines
a competely feasible thing in unix, and a nonsense in win*. The price of this
flexibility is the need of knowing the exact location of every component we
want to use.
