The list is open for admission all the time.

Does that mean the "user.home" property is not set? If it is set, what
value does it have?

I agree with this goal.

I agree with this as well. The question is whether the installer should
try and modify sys:etc/java.cfg. I would rather leave that as a manual
option that the admin can perform herself.

It is somewhat similar to the PATH envvar on Windows and Unix. After a
jython installation, you will have to edit the PATH yourself. IMO this
is a good feature of the installer. It shouldn't try to edit
autoexec.bat or ~/.login or the PATH entry in the windows registry.

Keeping all changes highly localized gives the user a good and secure
feeling that she still owns the computer.
