No, you can! With sudo. (BTW, when you make the teTeX trees belong to  
the group admin, set the umask value to 002, and become member of the  
group admin, you would have write and delete access to the  
directories. You could preserve yourself from deleting files. What I  
don't know is whether i-Installer respects this ...)

If you can launch X11 and either open an X11 Emacs or xterm, you can  
launch these X11 clients as running with super-user privileges. 'sudo  
-H xterm &' or 'sudo -H emacs &' launches them high privileged -- all  
the time, not only a few minutes as with sudo in a Carbon or Cocoa  
application as for example in Terminal.  Doing this empowers you to  
destroy the whole system within seconds. So you better accept that  
the system tries to protect itself from you and gives you all the  
while a time window to act deliberately. The better you prepare your  
work and the more you learn from earlier action the more efficient  
you'll become.

sudo is a universal concept. It works for all UNIX commands, it does  
not work for the usual GUI applications. Therefore you have the  
opportunity to 'activate' the root account as a login account. Then  
you would have unlimited access to system destruction.

A last way to make your live easy is to write shell scripts that you  
invoke with sudo -H.

Mit friedvollen Grüßen
