For better or worse the term ASLR is today in common use to refer to a
number of different approaches. Using what has become a generic term
allows the implementation to change in the future, without changing
the interface (e.g. sysctls, userland tools, etc.).

I wish there was a concise, technical comparison of the approaches
implemented by different operating systems, but I've unfortunately not
found one.
