PIE adds overhead (it can be quite a bit) both to binary size and
performance during execution. There are usually discussions about
kilobytes and this is well beyond that and space is still quite
precious on 8/16Mbyte flash devices. Most target platforms are
"slow" and have limited space to begin with, ASLR and PIE won't help.
Far from all supported platforms have NX-bit or equvalent which makes it
as I understand it less effective?
Effectiveness using vanilla Linux kernel seems to be questionable?
Interesting discussion about ASLR PIE in general here:
Debian seems to cherrypick applications
Perhaps the best solution wout be to provide two images, one with ASLR
and one without?
