Hi homme,
first of all:
I've tried to install using pacman -Syu cronie
This a bad idea, because this may break the system (please search the forum).
You can update the pacman database with "pacman -Sy", but please no full system update/upgrade.
The next thing is, that you should resize your image to fit the size of your sd card (hopefully it's big enough).
As i do not know what device and image you are using i'm unable to help with this.
