daemontools 1:0.76-3ubuntu3 (powerpc binary) in ubuntu vivid

 supervise monitors a service. It starts the service and restarts the
 service if it dies. Setting up a new service is easy: all supervise
 needs is a directory with a run script that runs the service.
 .
 multilog saves error messages to one or more logs. It optionally timestamps
 each line and, for each log, includes or excludes lines matching specified
 patterns. It automatically rotates logs to limit the amount of disk space
 used. If the disk fills up, it pauses and tries again, without losing any
 data.
