Yes, which is why I reset my passwords after doing "make install", which
worked fine. I suppose I should have mentioned that in the first message. :)

People installing the OS fresh won't need to take this step.

Note that 1,000 is simply too low -- the security value of PHK's scheme is
lost as computers increase in speed. Therefore, taking a minute to update my
passwords is acceptable to me. Since there is 0 cost for people installing
fresh, there is no reason not to do it.

The blowfish algorithm should also be similarly tuned.
