Note: F-Droid requires root privileges to install Privileged Extension as a system "priv-app". https://f-droid.org/packages/org.fdroid.fdroid can make use of system privileges or permissions to install, update and remove applications on its own. The only way to obtain those privileges is to become a system app. This is where the Privileged Extension comes in - being a separate app and much smaller, it can be installed as a system app and communicate with the main app via AIDL IPC. This has several advantages: * Reduced disk usage in the system partition * System updates don't remove F-Droid * The process of installing into system via root is safer Instead of this build, most users will want to install the "Over-The-Air" (OTA) update ZIP file is called https://f-droid.org/packages/org.fdroid.fdroid.privileged.ota. This is here to update Privileged Extension when it has been installed using the OTA ZIP.
