I made a replacement for
rootskel-gtk, using the previous version rootskel-gtk_1.27_amd64.udeb as the source, with a higher version number. I've changed the theme and the logo.
I've been told that the way to have the d-i use this new version is to rebuild d-i (preferably) or
the initrd (at least).
My question is, how do I rebuild the d-i and then how do I incorporate the new d-i in my build?
Cheers
