# Automated smoke test for the dirvish container.
# dirvish is a backup scheduler (not a network server), so the meaningful
# check is: the container comes up, the runit-managed services (cron +
# postfix) are running, and dirvish itself is functional (parses a master.conf
# and reports its version).
