you're right, randomization is in direct conflict with prelinking
(as it's called in the linux world), so you can have only one or
the other, not both (actually, with some extra logic you could
use a mix but it still wouldn't get back the full benefit of
prelinking). on the other hand, solaris has -Bdirect which is
another (and randomization compatible) way of speeding up runtime
linking, you might want to explore that path instead. there was
also a recent proposal for binutils to include -Bdirect [1].
