My system fails to upgrade. I suspect it was breached. Is there a way to compare system configuration to default version that should be at this date and kernel version?
My current system is Debian, but I am interested if any Linux flavor supports this feature.
I want to see what packages should be there by default, what extra stuff (and why) is installed, what packages are not official or have incompatible versions. I also want to see what files outside /home are not from those packages. Anything that will give me a hint about difference of server config from its default normal version.
