As you are posting to -current@, I expect you to report this issue  
about 14-current systems. As such: there was a "recent" change  
(2021-10-20) to the root entry to change the shell.
      
https://cgit.freebsd.org/src/commit/etc/master.passwd?id=d410b585b6f00a26c2de7724d6576a3ea7d548b7

By blindly accepting all changes, this has reset the PW to the default  
setting (empty).

I suggest to review changes ("df" instead of "tf" in etcupdate) to at  
least those files which you know you have modified, including the  
password/group stuff. After that you can decide if the diff which is  
shown with "df" can be applied ("tf"), or if you want to keep the old  
version ("mf"), or if you want to modify the current file ("e", with  
both versions present in the file so that you can copy/paste between  
the different versions and keep what you need).

Bye,
Alexander.
