This utility, inspired by the old SunOS 4.x intr(8) utility, will be used to start daemons with --detach and a timeout, like this: intr -t 5 kdc --detach || { echo failed to start kdc; exit 1 } This will allow tests to stop having to sleep poll for "started" output from the daemons they start, allowing them to run faster and to impose a reasonable timeout on daemon startup. The default timeout is 3 seconds.
