I’m surprised nobody mentioned Droidian yet. It’s the best of both worlds: You get a Linux phone with Phosh and an actual camera + sensors working due to the Android kernel. Check it out here: https://droidian.org/

It supports Waydroid out of the box, allowing you to run Android apps such as Whatsapp, Bitwarden and even Google Playstore, etc.

The new Firefox is miles away from what PostmarketOS offers. The only downside is you need a supported device, as per https://devices.droidian.org/.

So yes, I do drive Droidian daily, but I have an Android phone nearby just in case I need something specific.

I’m actually happy with Ubuntu. It is very stable and if you install Flatpak, you have another world of high quality apps to use.

/media is for removable drives. If you mount something there, file managers like Gnome will show you the “eject” or “disconnect” button.

/mnt drives show up as regular network drives without that “eject” functionality.
