I got a similar situation with my current openSUSE Tumbleweed system installed
with snapshot 20170429. I've reported it here:
https://bugzilla.opensuse.org/show_bug.cgi?id=1037927

Here is the output of `chkstat --system` (as in openSUSE Tumbleweed 20170810),
```
# chkstat --system
Checking permissions and ownerships - using the permissions files
        /etc/permissions
        /etc/permissions.easy
        /etc/permissions.d/postfix
        /etc/permissions.local
setting /var/cache/man/ to man:root 0755. (wrong owner/group man:man)
setting /var/log/lastlog to root:root 0644. (wrong owner/group root:utmp
permissions 0664)
setting /var/log/btmp to root:root 0600. (wrong owner/group root:utmp)
/usr/bin/at: unknown group trusted
/usr/bin/crontab: unknown group trusted
/usr/bin/fusermount: unknown group trusted
/sbin/pccardctl: unknown group trusted
```

So, it seems a problem with not only Live CD Image but also installed system.
