[rsbac] Trusted Path Execution and scripts

[Jens Kasten]

nice thinking.
one thing, can you show my an example script wich should harm the system?
on other thing is. for wath reason is the server running?
is it the a webserver with has some emailstuff there, there is no reason to 
give an user a account.
or is it a developserver. than mayby think about include also the other 
models.
the security it  alway restrikt the usability for an user and if  get an 
ordinary user more and more rights , the securtiy of the system shrink and 
shrink in the same way.
one point is not clear for me and this is the trusted script.
who say it is a trusted script and wich points must get ok that the script is 
trusted?
