After pkgbase updates, one should always scan for *.pkgsave and *.pkgnew
files (say via find) and then deal with possibly
merging/updating/restoring the content --or possibly just deleting the
*.pkgsave/*.pkgnew  file, as appropriate based on the content.

Do not forget to do something like:

# pwd_mkdb -p /etc/master.passwd.pkgsave

That would regenerate /etc/spwd.db (secure database) , /etc/pwd.db
(insecure database), and /etc/master.passwd --and the -p means it would
also regenerate a matching /etc/passwd as well.

Once you know the password related files are okay, you may want to
delete /etc/master.passwd.pkgsave .


You should also check if this pkgbase update or prior ones left any
other *.pkgsave or *.pkgnew files for you do deal with for finishing the
file updates involved. pkgbase does not deal with picking how some
configuration file updates should be done.
