Restore passwords from backup in new install

[romildo at uber.com.br]

Hello.

I want to do a fresh install of Fedora Core 1, as I
have been doing with each Red Hat Linux since version
3.0.3 in my home computer.

But now that I have more users in the machine, I am
wondering if there is a way to do a fresh install and
afterwards restore user passwords from a backup of
the old Red Hat Linux 9 install. This way users
will not have to set its password again on first
login.

Any clues on that?
