Re: Security hole in LXDE?

As a user and as I understand it you should not be able to make
system-wide changes and many packages affect other parts of the system.
A user can install and run any package that does not affect the system,
as a stand alone.  The system is a whole must be maintained by the
sysadmin for all users.  That is my simplistic understanding.
Unless it is specifically configured otherwise I don't see why these
assumptions would be wrong.  Imagine if I like MATE and the other user
likes X11 and I delete x11 and install MATE, or I install a package that
has dependency conflicts and replaces what is essential for the other
users' packages.

Live systems allow you to install whatever you like as they assume you
are the root or sysadmin.

At least that is how I understand security policy for this system.
