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.

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!
Andreas
