Hello! I was investigating this boot up error message : "failed to start verify of integrity of password and group files" It turned out to be due (apparently) to a faulty (re)installation of mariadb, which I seem to have fixed. Fine. But in the process, I came across this in my system: [localuser@localhost ~]$ systemctl status shadow shadow.service - Verify integrity of password and group files Loaded: loaded (/usr/lib/systemd/system/shadow.service; static; vendor preset: disabled) Active: inactive (dead) I am having some difficulty trying to find information on this. Bottom line: is this a problem, that I need to fix, or is it something that is normal and can just be ignored?
