Hello Rik,
and how on earth can you make "root" run that piece of code? Do you have
to specify it in the README section that it is mandatory to run that as
root in order the "new" application root will be installing to run as

Indeed, it is hard to tell what it actually does... unless you open your
eyes and see sed 's/root/something/g' somewhere.

Either way, installing from hundreds of source files, can make even the
best sys admin to not notice that part of the source code of the
BACKDOOR-contagious application!

bad PLAGUE! bad intentions! bad people possibly putting that where root is

Are you saying I just injected my system with an account with root
hiding somewhere? Please, clarify.

as you can tell by the subject, this is a BACKDOOR, you run it as root,
and yes, than it works and creates a "new root" account

you ran it as a normal user, so it won't work (you can't read
/etc/shadow as normal user (du'uh))
