Thanks for your detailed reply!
1. That's what I thought too. Sigh... I will have to lose some time then.
2. So, if I just use the Belenos repository I will get security updates, but
no newer versions. For that I need the backports. But where do these
backports come from? Ubuntu or Debian? And which branch? I honestly wouldn't
like to have stuff from Debian unstable in my PC, but would be ok with the
newer debian testing stuff. Maybe I am nitpicking, but I don't want to come
here complaining that Trisquel crashes a lot on my machine :P
3. When using netinstall what security is in place? HTTPS? GPG verification?
NONE??
4. Thanks! Grown used to unetbootin :P
