overlapping UID crisis

[Matt Juszczak]

hi all,

we had an overlapping uid crisis at work today.  I ended up writing a 
script to start at 30000 and increment by 1, to change all user's UID's 
(except system accounts)

Then I wrote a script that did a recursive:

chown -R $username:users /home/$username
chown $username:users /var/mail/$username

Is there anything i am missing?

We've been up all night and I just need to make sure my tired mind isn't 
forgetting anything.

Thanks,

Matt
