Where does Opensnitch version 1.5.2 and 1.5.8 save the rules? Not in home?

I have changed the Linux version by preserving my old home.
But now it looks like all my rules are deleted.

Edit:
It looks like this works:

1. copy the whole folder /etc/opensnitchd/ from your old Linux version to your new Linux version.
2. copy the file ~/.config/opensnitch/settings.conf from your old Linux version to your new Linux version.
3. Only then install Opensnitch 1.5.8

Question1: Is this the way that is thought to go?
Question2: Why are not all config files in Home? Why are parts of them in "/" ?

Normally all settings of a programme are in home. So when I keep my home, when I change the Linux version, I automatically have again all settings of such a programme after I have installed it in the new Linux version. But with Opensnitch it is more complicated.

Thank you.
