The class 10 SD card on my RPi failed prematurely and looking in to it I find that Arch ARM includes the dir /var/log/journal in the base image which enables persistent logging to the SD card. See the Storage setting in man journald.conf. Debian and Raspbian by default log the journal to /run/log, i.e. to RAM and I think Arch ARM should default to this also. Just remove that empty dir from the base image.
