Hi There,

If we look at current state of packages running inside GNU distros they 
are in very insecure shape which is either they are installed without 
sandboxing because the distro doesnt even provide that or no profiles 
exist for the sandboxing feature and has issues e.g:

- Sandboxing can be made through MAC (apparmor,selinux) or Using 
Namespaces (firejail,bubblewrap) But the problem with using these 
features it needs a defined/preconfigured profile for each package in 
order to use them thus making almost impossible case to be applied on 
every package in real bases. (unless a policy which saying no package is 
allowed without coming with its own MAC profile, but thats as well has 
another issue when using third party packages...)

- Containers are like OS, and to use it within another OS is like OS in 
OS i find it crazy and not just that the way that the package gets 
upgraded is not reliable to be secure so this wont solve our issue as well.

To solve this mess, is to use virtualization method and to make that 
happen is to put each package in a VM by itself means the package gonna 
use the system resources without being able maliciously gain 
anything.This provide less trust to developers and their code running 
within the system.

one of the greatest design made in our time towards security is 
GNU/Linux Qubes OS, it uses OS per VM and has VM to VM 
communication...etc i highly recommend reading their design to take some 
ideas from it:
