@george1421 That’s literally perfect, thanks! Seems fairly straightforward, I’ll update this thread with progress later.
As a note, we are charity refurbishing computers/laptops and donating them on. We have our own external database that we push data to but we use FOG to harvest data (we’ve created our own inventory and registration scripts to record all drives and pci devices and every RAM module separately). We also use FOG to image outgoing devices and to load tools like parted magic. We are now writing our own data erasure and verification script which is why we need to be able to sleep machines (in order to unfreeze drives), this will be used to effectively complete the automation of processing incoming items, currently we have to use external tools to perform data erasure and some of these we have configured to also report into our database but it would be quicker/more convenient to be able to do it all through 1 boot of the machine, hence adding the functionality to our FOS image.
