     Indeed, ???cow-store??? bind-mounts /mnt/tmp (or whatever the target mount
     point is) to /tmp to make sure we have enough disk space if we need to
     build things.  This was done in commit
     0adabad72d58492f08975af0b6b837ebde32a51b in response to a bug report.
     
     Is it a problem for the installer?
     

It's not an insurmountable problem.  But it is a bit annoying.
