This is currently an opt-in build flag. Once ASLR support is ready and stable it should changed to opt-out and be enabled by default along with ASLR. Each application Makefile uses opt-out to ensure that ASLR will be enabled by default in new directories when the system is compiled with PIE/ASLR. [2] Mark known build failures as NO_PIE for now. The only known runtime failure was rtld. [1] http://www.bsdcan.org/2014/schedule/events/452.en.html Submitted by: Shawn Webb <lattera@gmail.com> Discussed between: des@ and Shawn Webb [2]
