>Description:

When installing NetBSD-current/i386 from floppies, it now prompts for
each of the three install floppy three times (!), causing the user to
have to perform a total of nine floppy insertions.

A similar problem was reported in 2008 in PR install/38943 and
subsequently fixed.

The current problem appeared some time between CVS source dates
2010.03.12.21.37.37 and 2010.03.13.13.45.05.  There were 52 changes
committed during this time period; of these, the ones adding support
for CTF sections in the netbsd ELF image seem like a likely cause,
perhaps this one:

>How-To-Repeat:

Install NetBSD-current/i386 from floppies.
