Confirmed, /etc/default/passwd does not enable sha512. It's
probably a good idea and the easiest way to get SHA512 for people to
reset their password *AFTER* installing PAM. Might be worth adding to
the SHA512 wiki that PAM users can just do that.

Now to see if PAM supports blowfish without adding the library from
AUR?, I very much doubt it!


OpenBSDs bcrypt with configurable rounds is awesome by the way and far
more secure, yet wouldn't pass PCI compliance, how dumb some of these
certifications are.
