Default i386-current architecture switched to PIE

From an email from Theo de Raadt on the OpenBSD tech mailing list:

The i386 architecture has now been switched to PIE. There is a small
performance hit, but this part of ASLR is valuable combined with
W^X and the stack protector.

This is a non-trivial upgrade, so please be careful. Check the FAQ
for details or use a snapshot.
The original email can be found at http://marc.info/?l=openbsd-tech&m=138829916120601&w=2
For ASLR (Adress Space Layout Randomization) see https://en.wikipedia.org/wiki/Addres..._randomization
For PIE (Position-Independent Executable) on OpenBSD see http://www.openbsd.org/papers/nycbsdcon08-pie/
You don't need to be a genius to debug a pf.conf firewall ruleset, you just need the guts to run tcpdump
