Log on as root. warning

[alex <radsky@ncia.net>]

I don't understand the warnings about logging in as root
if all you intend to do is make some changes that only root
can make.  What difference does it make if you do su
or log on as root?  Doesn't a root mistake have the same effect
either way?

I can see why it's not advisable to run internet as root or
just not necessary if you will be making changes that a
user can make.

Doesn't root=root regardless of how you become root?
Ditto for user?

Can someone justify the warning?
