Thanks for the response. I don't understand how software ignores the
rounds value specified in /etc/shadow but honors the salt specified in
same. Assuming should only happen if /etc/shadow omits $rounds=.

The context is the local shadow file in both the Fedora (above) and OS X cases.

If the environment is using directory services (Active/Open Directory,
LDAP) then I could even be using an OS X 10.6 system for this, using
the same password. And all such setups are kerberized and hence
standardized.
