2-8. Q:
Some processes in DRD, particularly drd clone and drd runcmd, take a significant
amount of time. Can these processes be interrupted?
A:
All DRD processes, including drd clone and drd runcmd, can be safely interrupted
issuing Control/C (SIGINT) from the controlling terminal or by issuing kill -
HUP<pid> (SIGHUP). This action causes DRD to abort processing and perform any
necessary clean up. Do not interrupt DRD using the kill -9 <pid> command
(SIGKILL), which fails to abort safely and does not perform cleanup.
