those of you who use libtaskotron from git, please note that libtaskotron now requires one
more directory (/var/cache/taskotron) to exist . From now on, you should be notified if
you're missing any of the important directories right at 'runtask' execution
start (the execution will exit in that case).
I have also added this directory into conf/tmpfiles.d/taskotron.conf, so if you use
automatic pruning of taskotron directories, be sure to update this file in your system.
