Eelco Dolstra	dcc433de47	* Operation `--delete-generations' to delete generations of a ... 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.	2004-09-10 13:32:08 +00:00
Eelco Dolstra	00fe1a506f	* When creating a new generation, also make the normal form of the ... derivation (i.e., the closure store expression) a root of the garbage collector. This ensures that running `nix-collect-garbage --no-successors' is safe.	2004-02-11 10:25:31 +00:00
Eelco Dolstra	06a75a7e0c	* A command `--switch-generation' to switch to a specific generation ... 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.	2004-02-08 14:07:43 +00:00
Eelco Dolstra	b8675aee54	* In `--list-generations', show what the current generation is.	2004-02-06 16:16:55 +00:00
Eelco Dolstra	73ab2ed4fd	* A command `--list-generations' to show all generations for a ... profile.	2004-02-06 16:03:27 +00:00
Eelco Dolstra	7c0fa4474f	* More refactoring.	2004-02-06 14:57:10 +00:00
