Rollbacks
When you perform a home-manager switch and discover a problem then
it is possible to roll back to the previous version of your
configuration using home-manager switch --rollback. This will turn
the previous configuration into the current configuration.

Home Manager Rollback
Imagine you have just updated Nixpkgs and switched to a new Home Manager configuration. You discover that a package update included in your new configuration has a bug that was not present in the previous configuration.
You can then run home-manager switch --rollback to recover your
previous configuration, which includes the working version of the
package.
To see what happened above we can observe the list of Home Manager generations before and after the rollback:
