[solved] Messed up Pam upgrade, now can't su and....

So this is totally a why you shouldn't upgrade while tired, but hopefully it's salvageable.... I ran my weekly emerge -Dua system, which complains about the pam upgrades, pointing to the guide. I go to the guide, and run
qfile -o /etc/pam.d/*
as instructed, which showed like two things. I keep reading, seeing how you can probably get rid of that stuff, and not thinking I do a
rm /etc/pam.d/*
and then the doom starts creeping in.... So I can't su, I'm not sure what else to check. I hadn't done any custom configuration or anything, but I'm not sure what all I need to remerge before I log out and get screwed.... Or just restart something? Please help.

Can’t help you with your exact problem but keep in mind: A live cd can help in these cases. If you can't login as root just boot from live cd, chroot into your gentoo install and fix the problem. That’s at least better than starting from scratch.

Probably re-emerging pam and some other packages from the chroot will fix your problem as it will re-install the config files into /etc/pam.d/. To get the complete(?) list of packages which install into /etc/pam.d/ do a

Thanks. Having slept on it now, some more info:
-I have installed the new pam, that's why a lot of early info is missing, I hoped reinstalling pam would fix it, and it overwrote that stuff.
-When I say "can't su" I mean it skips directly to authentication failure, not even asking for password. The same happens if I switch virtual terminals and try to log in as my normal user
-I tried using passwd on both accounts and get: Authentication token manipulation error
-I ran the equery and got:

sys-process/vixie-cron-4.1-r10 (/etc/pam.d)

And remerging shadow has at least made me able to login/su again so I can go on to the rest of the list in peace. Thanks.
