I like the `addable()` idea. I would even propose that we also create helper function to capture the logic of clear persistent volume info from a disk resource. ``` Try<Resources> backToDisk = grow.volume().clearPersistentVolume(); ... ``` notes: also add: `!isEmpty(addition), !isPersistentVolume(addition)` - Zhitao ----------------------------------------------------------- This is an automatically generated e-mail.
