2 years ago I made a study on Linux distributions and default security wrt. automatic updates.

I should redo that and follow up.

I know for a fact that:
Debian will fail, cause they still haven't had an release.
CentOS will fail, same reason.
OpenSuSE will fail
Fedora Desktop gets a maybe
Fedora Server: Unknown
Fedora Cloud: Unknown
Ubuntu might succeed

Maybe I shouldn't bother.

@Spider i use debian stretch ; don't fix your eyes on official release ;)
@Spider @ando Also, be careful with automatic updates. I had it running on a remote Debian box once, and an sshd update broke it and left me locked out.

@yair @ando The risk with Automatic updates is _far_ lower than the risk of installing systems and not doing updates.

Admins that complain can always disable it. It is reckless to ship systems without automatic security updates by default.
