A Recommends, or even the looser Suggests is quite harmless and for first
timers, I think it would help a lot.. At least that will give you (me) an
idea that there's a fundamental decision I need to make.

Any link to where i can read up on that?

Dang :(.

Yeah, in practice that's exactly what happens when you add all
testing and remove jessie backports.

Packages will always be newer in Testing, so dpkg/apt will use
that..

But all packages is installed just fine now and from what I can
see, they also all work as expected.

As expected one could assume when I don't have a compute. I was
hoping I didn't need to install that manually..

Feel free to link me to one that's actually up to date and in a language
that's easy to understand AND talks about the different options..

Well, I'm not sure I'll be doing that.. Last bugs I filed was closed right
away without closer not understanding the underlying problem.


But I'll be reading that doc from cover to end!

Yeah, but then I'll be in the same situation as before - I don't have
the foggies idea what I'm doing and I'll keep pestering everyone till
I do :D

Better to take the bull by the horn and tell him/her who's the boss right
away - saves a lot of grief in the long run. :)

Who might now? Last chance to get rid of me :D



After starting to at least have a glimmer of idea what everything is,
and how they work together, I started looking at logs (in more detail!! :)
and actually started to understand what they're where saying. So after
basically purging and then installing most of the service packages, I'm
now down to a measly 0.53 in load :D

I'm pretty sure that means I have a reasonably solid base to build on.
