'forgot' password ? Couldn't generate salt

[Michael Cheponis <michael.cheponis%gmail.com@localhost>]

I did a sysupgrade to amd64 to _RC5  (from _RC3), but it seems to have reset my passwords.  The accounts are there, just the passwords have been changed.

Tried logging in single-user as described in https://www.netbsd.org/docs/guide/en/chap-boot.html

# passwd root

...

Couldn't generate salt.

Unable to change auth token: Error in service module

#

And of course, the password is not changed, and I still can't log in.

I'm probably doing something dumb.  Thanks for any help/pointers.
