>Description:

NetBSD-current/i386 has recently started prompting for each install
floppy twice, causing the total number of floppy insertions required
to install to jump from two to four.

The problem appeared some time between source date 20080516-1010 EET
and 20080602-2224.  It is still there at 20080611-1128 EET.

On June 3, I sent a message to current-users asking whether this
change is intentional.  As I received no response, I assume it is not.

>How-To-Repeat:

Attempt to install NetBSD-current/i386 from floppies.
