Yeah... you will probably get away with just copying over the old
password files... however you should take care doing it, there may
be new important system accounts in the defailt password files in 9
Things might go a little screwy if they are missing or there are
incorrect entries....
I've done this numerous times and got bitten by the missing mailman user
problem* where cron jobs would fail and eventually fill up /var with
zillions of error logs (what the frik is wrong with one error log ??).
The files you need to copy would be:
/etc/passwd
/etc/shadow
/etc/group
/etc/gshadow (perhaps)
Just take some time to check that all the system accounts/groups exist
and that their shell / home directory / group entries are correct...
You could use something ugly like the following to check for missing
accounts...
awk -F: '{print "^" $1 ":"}' old_passwd | fgrep -vEf - new_passwd
Other things that you have re-configured yourself may need some looking
into... random services, global shell rc scripts, global configs, etc...

* Alternatively called, accidentally installed the mailman package as
"Install Everything" is considerably easier on ReadHat.... :)
