>Description:
Per my mail to -current of 16 September 2011, I had an old scratch box with 7.4 on it, that I wanted to try the installer out on.  I figured I could just reuse the partitions for testing (even though this is in general risky, due to stale libraries/configuration files/etc.), but was unable to do so.  The extracting stage died with an error about being unable to create /var/empty with appropriate permissions.
>How-To-Repeat:
Try to install 9-beta2 on existing partitions
>Fix:
Either the /var/empty errors could be worked around, or the installer should refuse to use existing partitions.
