devvm retention

Show or change what devvm deletes on its own

Synopsis

Show the retention settings, which say what devvm deletes on its own, or change them with KEY=VALUE, and KEY=off turns one off. The keys are logs.runs, history.age, history.count, tools.unused-age, orphans.age and nix-cache.size, and every setting is off until you set it. devvm applies them at most once a day, except orphans.age, which only devvm gc –retention applies, and they never delete a VM, an image or a shared tool any VM has.
