Yes, LTS, thanks Liam. Only LTS has life cycle of mere 2 years, whereas
RHEL (hence CentOS) is what, 10 years? I was pretty sure Debian does not
backport patches (of Linuxes no one except RH, as far as I know). How do
they do it with LTS? Do they just freeze major version, no matter what (it
is only 2 years the need)?
