Arch Problems and Troubleshooting
Known Issues
Bluetooth
When hibernating or asleep for too long, the bluetooth driver turns itself off and does not properly connect with the headset.
Solution:
Shutdown the system, unplug from power source, plug, turn it on again.
Root Disk Space
Apparently 20gb is not enough for the root / dir.
Workaround
Clean the pacman cache with pacman -Scc
Actual Solution

I don't think there's an easier way. You need to copy the data from one partition to the other. You need to delete the old home partition and resize the root partition. That cannot be done on a running system, so a live CD or USB seems like as good as it gets.
Boot the live CD/USB.
Mount the root partition to /mnt/root.
Mount the home partition to /mnt/oldhome.
Copy the data using rsync:
sudo rsync -avz --hard-links --numeric-ids /mnt/oldhome/ /mnt/root/home
Open /mnt/root/etc/fstab and delete the entry for your home partition.
Unmount the root and home partition and reboot the system. If everything works as expected you can reboot again into the live system and then:
Open Gparted.
Delete the old home partition, resize the root partition.
That should be it.>
