Name
nix-env --switch-generation - set user environment to given profile generation
Synopsis
nix-env {--switch-generation | -G} generation
Description
This operation makes generation number generation the current
generation of the active profile. That is, if the profile is the path
to the active profile, then the symlink profile is made to point to
profile-generation-link, which is in turn a symlink to the actual user
environment in the Nix store.
Switching will fail if the specified generation does not exist.
