In the case when a vg name was not pre-seeded, nor was the hostname, the "automatic" auto-select defaults can end up clashing with real device names. '-vg' suffix to the auto-selected vg name was a minimalistic hack to bypass the problem. I have tried to come up with a better / cleaner solution, but didn't come up with anything more elegant for the case of VG name clashes (from a pressed, from user entry, from auto-generated name) with an existing device name.
