Well, what do you want to do? Change to debian stable or only using pure debian sid/unstable and it's kernel?
"siduction" is more than 90% debian sid/unstable btw.
Yes it is possible to stay in unstable without the siduction-scripts, kernel and fixes (if one needed).
Disable the siduction source lists, remove all siduction related packages, install the debian kernel and remove the siduction kernel, if you really want, than you have a pure debian unstable/sid
How to migrate back to stable? I don't know, best is to install a stable debian from scratch .
Ah, one thing, please change the name from Diduction to siduction!
