It seems to work: I rolled back from 21 to 20, 19, 18, 17; then removed a package and am at 18 now. Then removed another package and arrived at 19, where the previous 18 and 19 were overwritten. Personally, I would have deleted all (consecutive) generations starting with 19 after the first roll-back and additional package removal; now we still have pieces of old history lying around, the (old and) current 20 is not a successor of the current 19 any more. But I can also live with the current situation. Am Sonntag, 27.

It works also: building path(s) `/nix/store/2gkfim0yry8sii7vhxwcivkbnfpaiqiq-user- environment' building user environment `/nix/store/2gkfim0yry8sii7vhxwcivkbnfpaiqiq- user-environment' with 0 packages... switching from generation 1 to 0 Thanks!
