ocs_postrun, ocs_postrun1, ocs_postrun2... is intended for running a command after an operation of saving/restoring an image or cloning disk/partition has been completed. E.g. ocs_postrun="/live/image/myscript.sh". If you have more commands to run, you can assign them in the order: ocs_postrun=..., ocs_postrun1=..., ocs_postrun2=.... If more than 10 parameters, remember to use ocs_postrun01, ocs_postrun02..., ocs_postrun11 to make it in order. //NOTE// If you use this parameter, remember not to use "-p reboot" or "-p poweroff" option of ocs-sr. Use "-p true" instead because if "-p reboot" or "-p poweroff" is used, it will reboot or shutdown the system before ocs_postrun related commands are executed. For more info, check this discussion.
