Questions as I read: disable_root


The default behavior in some linux distributions is to disable login to root regardless of where the user is coming. Having a way to set this, regardless of the distro default I see as a big plus - HOWEVER, from an AIX viewpoint I have a question/comment.

Within AIX (and maybe Linux, freebsd, et al) it is possible to distinguish between login from a remote location (i.e., via network) or "local" - via console or physical COM (rs232) port. I expect the cloud-init model is as I have experienced (limited) Linux. Login is available/permited regardless of "wherefrom", or it is denied - regardless.

What I would like to see (read, what I recommend) for root on AIX, is that by default "remote" login is disabled, but "local" login is permitted. In other words, login via a virtual console (via HMC or IVM) is permitted, otherwise - not.

So, I would add an extra setting:

disable_root: false|true|remote

and the default is true for cloud-init (aix distro would change it's value to remote).
