What will got carried over in rebasing?

Project Discussion

I start with installing Kinoite from booting USB media.

I created /dev/bcache0, which is working with a ssd cache and hdd backing .

Then I rebased to Silverblue. After boot into Silverblue, I find that /dev/bcache0 is not defined.

Is this a normal behaviour? Can I make virtual devices created in one base (Kinoite) also accessible to other bases (Silverblue) ?

Will it be the same if rebased from F34 to Rawhide and vice versa?
