I would like to add a run once command to sysprep to ZAC Reg my devices. I've noticed that sometimes after imaging the runonce command runs so quickly on the first login that the zac reg command fails. (At least this is my assumption)

Is there a way to to delay the run once? The current runonce command looks like this.

Command0= zac reg http://zen.domain -u user -p pw

any ideas? Ideally a 20 second delay would be great.
