What is the advantage of making f-droid a system app? F-droid (0.7) has two options:

One to grant it "root" powers, and another to give it "system-app" powers.

Just using it as a "root" app will let it install apps without going through the whole "Are you sure you want to install this app" page.

What does System-app give it?

I can't test it as it crashes on my phone
I believe this was/is a planned feature for F-Droid, which would essentially give it features similar to the play store where it can auto-update apps, install them and remove them all by itself, without needing user interaction. See this as an explanation - it's the extension which was meant to give F_Droid these priviledges, but as it says in the description:


  Note: This is still in a testing phase. Current F-Droid versions do not yet interact with this extension.
