Feature request: dynamically grow COW file #53

Closed catphish closed 8 years ago

catphish commented 8 years ago

it is technically feasible to have the space allocated for the COW data to grow dynamically whenever it nears being full, rather than having to choose a fixed size for the file in advance?
