Read MoreSaltStack .sls file to allow root to log in directly
I’m lazy and I have bad admin habits, like logging into a LINUX server, directly, as root. Worse than that, I like to set the passwords all the same on the systems. But, this is just my Raspberry sandbox network so nobody cares. I wouldn’t dream of such a scheme in production. But now that […]
