Just like the title says I want to turn an old tablet of mine into an ereader.

The tablet in question is samsung galaxy tab 3 in which I installed postMarketOS.

I installed the console version, and once everything was set up I ssd into the machine and installed the following packages :

greetd, greetd-openrc, cage, fuse

Downloaded koreader app image into /bin/

Activated the greetd service

rc-update add greetd default

and configured /etc/greetd/config.toml with the following

[terminal]

vt = 1

[default_session]

command="agreety -c sh"
user="greeter"

[initial_session]

command="cage -s -d -- koreader"
user="me"

and rebooted the tablet, however I am still greeted with the login prompt no matter what I do.

Any tips on how fix this or a other way I could accomplish my goal?
