Hi. I had the same problem and this solution was really helpful. However, I was able to do this without an installation CD. From the login screen, I did a
then boot into failsafe mode
. As a bonus, when it reboots, it tells you what drive the operating system is on and asks you if you would like to mount it to /a. Here is my whole procedure:
From the login screen:
Stop A
At the {1}ok prompt:
boot -F failsafe
Screen echoes that it has found the disk with the OS and do you wish to have it mounted read-write on /a. Choose:
y
Instead of using EDIT command, you can use VI by entering
TERM=vt100
Export TERM
Edit the password file:
vi /a/etc/shadow
Use ghjk to navigate to the hashed password (between 1st and 2nd colons), then x to delete the characters.
Save the file:
:
w!
Exit the file:
:
Q
Power the machine off, then back on.

Hello All,

rescue
RESCUE(8) BSD System Manager's Manual RESCUE(8)NAME
rescue -- rescue utilities in /rescue
DESCRIPTION
The /rescue directory contains a collection of common utilities intended for use in recovering a badly damaged system. With the transition
to a dynamically-linked root beginning with NetBSD 2.0, there is a real possibility that the standard tools in /bin and /sbin may become non-
functional due to a failed upgrade or a disk error. The tools in /rescue are statically linked and should therefore be more resistant to
damage. However, being statically linked, the tools in /rescue are also less functional than the standard utilities. In particular, they do
not have full use of the locale, pam(3), and nsswitch libraries.
If your system fails to boot, and it shows an error message similar to:
init: not found
try booting the system with the boot flag ``-a'' and supplying /rescue/init, which is the rescue init(8), as the init path.
If your system fails to boot, and it shows a prompt similar to:
Enter full pathname of shell or RETURN for /bin/sh:
the first thing to try running is the standard shell, /bin/sh. If that fails, try running /rescue/sh, which is the rescue shell. To repair
the system, the root partition must first be remounted read-write. This can be done with the following mount(8) command:
/rescue/mount -uw /
The next step is to double-check the contents of /bin, /lib, /libexec, and /sbin, possibly mounting a NetBSD installation CD-ROM and copying
files from there. Once it is possible to successfully run /bin/sh, /bin/ls, and other standard utilities, try rebooting back into the stan-
dard system.
The /rescue tools are compiled using crunchgen(1), which makes them considerably more compact than the standard utilities.
FILES
/rescue Root of the rescue hierarchy.
SEE ALSO crunchgen(1)HISTORY
The rescue utilities first appeared in NetBSD 2.0.
AUTHORS
The rescue system was written by Luke Mewburn <lukem@NetBSD.org>. This manual page was written by Simon L. Nielsen <simon@FreeBSD.org>,
based on text by Tim Kientzle <kientzle@FreeBSD.org>.
BUGS
Most of the rescue tools work even in a fairly crippled system. The most egregious exception is the rescue version of vi(1), which currently
requires that /usr be mounted so that it can access the termcap(5) files. Hopefully, a failsafe termcap(3) entry will eventually be added
into the curses(3) library, so that /rescue/vi can be used even in a system where /usr cannot immediately be mounted. In the meantime, the
rescue version of the ed(1) editor can be used from /rescue/ed if you need to edit files, but cannot mount /usr.
