Re: How do I get group "trusted" onto my system?
Checking a Tumbleweed system, I see the line
in "/etc/groups". The line appears to have been added some time after the Tumbleweed install. The number "461" is probably just the first unused number in a range, so might not be significant.
The date on "/etc/group" is todays date -- at about the time of my most recent update.
There is a package "system-user-root" but I am not seeing much information on it. You could always try a forced re-install of that package.
