'x' means look in /etc/shadow, '*' is one of several ways of indicating "no
password" as in you can't log in, rather than "blank password" which lets all
log in without one. The .rpmnew is the "unconverted" form, if you run pwunconv
you'll see the same it /etc/passwd.



The /etc/passwd.rpmnew has 15 lines of userid stuff...
My /etc/passwd file has a lot more than that... and many I didn't even know about.... (various system things ntpd blah blah blah)

Am I supposed to take the users that *I* added to the system (via system-config-users) and cut/paste those ones into the new one, changing the x to an *? And thereby dropping all those other ones that are set to nologon anyway?

Does pwconv or pwunconv do this for me automatically? (The man file looks great for people familiar with it... not so great for explaining what the commands really do.) Shouldn't the update script have done this when it updated setup?

       The pwconv command creates shadow from passwd and an optionally existing
       shadow.

       The pwunconv command creates passwd from passwd and shadow and then
       removes shadow.

So where does passwd.rpmnew come into play?

pwconv ... and removes shadow... um, don't I need shadow?
ditto for pwunconv

I don't get it, now I don't know what I have. :-(
