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.
