I wanted to try dual booting on both my phones. My devs have posted that we should check out our /system partition and see if we have enough space, a simple 'DF' through a terminal emulator. What I saw surprised me. I've used Linux for a long time and this is the first I saw this kind of behavior.
Many apps/games have their own 'hidden' partition. An unisntallation doesn't technically 'fix and merge' said uninstalled app and add to whichever partition they stole it from (can someone confirm which, I'd like to know).
I'd like something that can do this for me, and to scan whether or not a new-going-to-install app will do this to me. I don't have the Play Store installed, so I manually install them from sites I trust.
(hopefully used the 'security' tag correctly, as I feel this is a 'forced' aspect)
