Security and PAX

[rhino64%epost.ch@localhost]

Hi,
  I am quite new to netbsd and I am curious about 
the security mechanisms available.

In the security page "http://www.netbsd.org/support/security/";,
I can see that the PaX module is used in the kernel
but without any other information.

What should be done in order to use (and perhaps configure)
that feature?

Sould the executables being compiled with the "-fpie" option?

Any comment would be greatly appreciated?

kind regards,
