No, it should be the same.  Look in the root/.ssh/authorized_keys file to see 
if 
the ssh-copy-id command put the right thing there.  And make sure the file and 
directories above have the right owner/permissions.   I've seen some versions 
that want to use a file named authorized_keys2 instead but I'm not sure exactly 
why.
