This is how Lazarus is installed by default (distributed packages). This 
may be okay for multi-user systems with a skilled administrator, but not 
necessarily for the average user at home. All my current considerations 
are about users (like me) without an skilled system administrator.

This requirement should be documented, including how to accomplish it. 
The documentation could be restricted to how to use the repository, when 
  Lazarus ever has to be rebuilt after the first installation - if 
that's the simplest way.

Remember that installing packages requires to rebuild Lazarus, so that a 
private installation might be preferable as the default. While this is 
not complicated for itself, it should be nice and easy to perform the 
move from the original distribution to a private build.

It's not so hard for the second time, but for the first time it is. 
Perhaps I see too many problems, I'll have to check the actual 
procedures myself again.
