I've got a strange error.  I was trying to add auser w/ addnerd.  Then
changed
my mind and tried to delete him and now I get an error message that says
at
boot 
'root password may be incorrect -- /etc/ptmp exists'
and when I try to add another user w/ addnerd it says the password file
is busy
and to try again latter.

I don't just want to delete /etc/ptmp cause I'm not sure if I need it. 
Any
Idea what I did wrong?

TIA.

Gerald
