Hi Papio,
yesterday I donwloaded this new iso and I tested under these conditions, under last version of MOS updated and with a Chrysalis pack already installed, well, and mounted the ISO the installer show me this mistake:
"You need 1200 octeds free to install the pack Chrysalis."
Also other message form system this in spanis: "Reinserte el volumen en la unidad 218"= Reinsert the volume in the unit 218"
I know this is not way to test your pack because it needs a clear installation but this other tests that I hope help you.
I like the logo in the installer.
