NetBSD SS.Culver.Net 10.0_RC5 NetBSD 10.0_RC5 (GENERIC) #0: Tue Feb 27 05:27:39 UTC 2024  mkrepro@mkrepro.NetBSD.org:/usr/src/sys/arch/amd64/compile/GENERIC am
>Description:
1. Used sysupgrade to go from _RC3 to _RC5
2. Somehow, that cause the spwd.db password database to change
3. All passwords were changed, I could not log on even to root

4. I saved /etc so I copied into /etc a previous version of spwd.db
5. This allowed logging in to the machine.
6. passwd always fails henceforth like this:

# passwd mac
Changing password for mac.
New Password:
Retype New Password:
Couldn't generate salt.
Unable to change auth token: Error in service module
#

7.Note was root user; cannot change any password, not even root
passwd.conf:    localcipher = argon2id
