NetBSD-current no longer boots after install

[Andreas Gustafsson <gson%gson.org@localhost>]

Hi all,

Some time between CVS dates 2010.01.14.12.05.15 and 2010.01.15.01.00.46,
a bug was introduced that causes the initial boot of a freshly
installed NetBSD-current system to fail with the following errors:

    boot device: wd0
    root on wd0a dumps on wd0b
    WARNING: No file system modules have been loaded.
    no file system for wd0 (dev 0x0)
    cannot mount root, error = 79
    root device (default wd0a): 

The INSTALL_FLOPPY kernel boots fine, and syinst works; it's only the
GENERIC kernel of the installed system that fails to boot.

On i386, the bug can be reproduced by installing misc/py-anita from
pkgsrc (you need version 1.9 or newer) and running the shell command

    anita interact

The following commits were made between the last known good version
and the first known broken version:
