2004-09-10 * Operation `--delete-generations' to delete generations of aEelco Dolstra1-0/+2
profile. Arguments are either generation number, or `old' to delete all non-current generations. Typical use: $ nix-env --delete-generations old $ nix-collect-garbage * istringstream -> string2Int.
2004-02-11 * When creating a new generation, also make the normal form of theEelco Dolstra1-1/+2
derivation (i.e., the closure store expression) a root of the garbage collector. This ensures that running `nix-collect-garbage --no-successors' is safe.
2004-02-08 * A command `--switch-generation' to switch to a specific generationEelco Dolstra1-0/+8
of the current profile, e.g., $ nix-env --list-generations ... 39 2004-02-02 17:53:53 40 2004-02-02 17:55:18 41 2004-02-02 17:55:41 42 2004-02-02 17:55:50 (current) $ nix-env --switch-generation 39 $ ls -l /nix/var/nix/profiles/default ... default -> default-39-link * Also a command `--rollback' which is just a convenience operation to rollback to the oldest generation younger than the current one. Note that generations properly form a tree. E.g., if after switching to generation 39, we perform an installation action, a generation 43 is created which is a descendant of 39, not 42. So a rollback from 43 ought to go back to 39. This is not currently implemented; generations form a linear sequence.
