After a lot research on distros I got more confused. I was happily living with my lubuntu and
apt-get for years. Then I came across a system format and my digging started. Finally I arrived to Debian stable.
Now if I install Debian 7 stable and there happens to be a release of Debian 8 stable, would I be able to switch it without booting installing any other distro? I really do not want to go to testing or unstable. So one line my purpose is to fully avoid reinstall nix system after a year or two.
My purpose is simple programming. I heard about arch, but I have not much time to get deep learn.
