That was not meant as an insult to your work, and I'm terribly sorry if it 
arrived that way. Honestly, Discover is a fine piece of software, especially as 
a software store and I quite enjoy using it as such. However, I think you're 
right, my observations toward the "very, very flawed" might be better directed 
at PackageKit since it doesn't have the capability to do autoremove like I'm 
suggesting for software updates.

Ubuntu's update-manager does have this capability, as it's using apt directly 
on the backend as opposed to using PackageKit as an abstraction layer. This 
may be why it has an advantage in terms of functionality that PackageKit (and 
Discover, by extension) cannot provide in this regard.

This has the benefit of removing outdated kernel packages which prevents a 
user's /boot volume from overfilling. One usually sees a separate /boot volume 
on LVM or encrypted LVM/LUKS systems. This is not something that Discover does 
automatically, which unfortunately causes a user to have to remember to run 
"apt autoremove" from the command line manually, if they even know to do that. 
unattended-upgrades is supposed to take care of this, but it doesn't always 
work in my experience.

At any rate, those are my thoughts at the moment. Thanks for chiming-in, and 
let me know if you have any more thoughts on the matter. :)
