+## Update all flakes
+
+With `bento flake-update` you can easily update your flakes recursively to the latest version.

+A parameter can be added to only update a given source with, i.e to update all nixpkgs in the flakes `bento flake-update nixpkgs`.

 # CAVEATS
 
 - if you propagate a new version while a host is updating, it may be incorrectly seen as "up to date" because the log file deposited will be newer than the `last_time_changed` file
