Can't install if another disk with an existing vanilla os install is connected to the system

This is pretty much impossible to fix with the way that the installer currently works.

It creates lvm volumes and labels partitions with predetermined names. (for example vos-root and vos-init)
Fixing it would either mean to make all of that configurable or random.
While this is possible, it would require major changes.

Maybe detecting an existing vanilla installation and warning the user might be a good temporary bandaid.
