(232921) somewhat random pw-related errors following system upgrades (was: freebsd-update(8) without an echo of "You must be root to run this.")

Sudo means that you are root.  *LOCKED* just disables the root password.

Thanks for the clarification.



As background: I spent many hours repeatedly testing freebsd-update 
upgrade from 12.1-RELEASE to 12.2-RELEASE-p3 (and greater) in virtual 
machines, trying to understand why (a bug) mysql57-server would not 
install following an upgrade with the root password _disabled_.


Later tests included multiple consecutive successes (bug-free) with the 
root password _enabled_ – enough consecutive successes for me to assume 
that the bug was somehow caused by the *LOCKED* aspect.


That period of consistent success was followed by reproduction of the 
bug with the root password _enabled_, at which point I realised the 
wrongness of my assumption. Confused by the randomness, I began to 
wonder whether – in rare situations – sudo might be not entirely effective.


Eventually I realised, the failures to install mysql57-server were 
symptomatic of FreeBSD bug 232921 
, which 
involves pwd_mkdb(8).


I'll not attempt to understand why bug 232921 was not consistently 
reproducible during my tests, but I'm glad that it's unrelated to 
disabling the root password; and I no longer doubt the usefulness of 
sudo :-)

The following components of FreeBSD seem to be installed:

The following components of FreeBSD do not seem to be installed:

Does this look reasonable (y/n)?
