I thought of a concern about this system, root isn't exactly safe

I mean that is not exactly a safe thing to do even if it is just a toy. Couldn’t a simple sudo and a regular login be enough? Or is there a reason that the system has to be root?

The OS is on a separate partition and has pretty much all access removed - to the point where an update basically just downloads the entire OS again and writes it to the partition.

A separate partition that the basic user still has root access too, (I checked, I can SSH in and destroy the underlying system easily, heck I can really mess it up using SMB and my android tablet.) So that really doesn’t put my mind at ease about it. Granted it is Linux and it is quickly reinstalled if something goes wrong, but with it being a username:root Pass:root it’s incredibly easy to access anybody’s Lakka system if you happen to get on the same network.

Even when installed to the system? It runs like a Live Linux Distro? Or are you thinking in terms of the flash drive? If it runs like a Live Distro even when installed to the system then I guess that would be a pretty safe method there.

The rootfs is a read only squashfs. The only place where the user is allowed to write is the partition containing roms and saves. So it’s 99% like a live system, even when installed. The 1% left are there to make this live system persistent.

Thank you for clearing up that concern.
