True, and can't be said better. And that was one (not the main though)
reason I migrate to FreeBSD servers whose time came instead of upgrading
them to more "Desktopish" Linux (took me a lot of effort to not repeat
here someone's "Windoze" comparison). I know I have no guarantee, but they
(FreeBSD) have good record... Workstations though stay with CentOS (7
now).
