Reset your SLE/openSUSE Linux default file system permissions
Let’s say you’ve cd to / and chown -R me:users * and you now have a system that has corrupted permissions. Have no fear, the SUSE team is here to the rescue. Simple run this command as root and you’ll be back up and running in no time:
SuSEconfig --module permissions
