Arch Linux

I was using a fresh installation of Arch and tried to install the unifi service to manage my UbiQuiTi APs. The service always failed with the following output:

[root@...]# /usr/bin/java -jar /usr/lib/unifi/lib/ace.jar start

I was able to fix the issue by installing the fontconfig package, as the log files indicated that fontconfig was expected but missing.
