How to use microSD card to extend storage on arch linux Phosh

[pineuser0]

Recently installed arch linux phosh on my pinephone, but the storage apparently ran out before I could even download anything to the phone, or do any other storage-related tasks.

Something is wrong, unless you are trying to run on a 4Gb SD-card? Arch will resize the root partition during first boot (and you will see the text messages on the screen) - my full arch installation with several added applications takes only 5.4Gb of disk. So I suspect the best thing to do would be to reinstall arch.

I assume you are using a Danct12 image?

What I'm trying to do is use my 128GB microSD card that I have just dd'd with /dev/zero as a method to extend the storage of my pinephone, thus letting me use it regularly. How can I accomplish this?

There are many ways to utilise the SD-card for additional storage: all the standard Linux options apply, but instructions for example to use it for the /home directory are here.

A reinstallation fixed the problem, the image used both before and after was: https://github.com/dreemurrs-embedded/Pi...908.img.xz
