--- Comment #20 from Jeremy Newman jnewman@codeweavers.com --- Verified that it is working now. I did need to add a trailing slash after filename on the directory purge line. It does not seem to actually purge without it.
I'll create an systemd script and keep this running in the background. Should hopefully prevent future issues.
