Description
Is firecracker supporting unmap/discard/fstrim, ie automatic reduction of the image size on the host when a file is deleted on the guest? If it does how do I enable it?
Contributor guide
Research direction
No files, tests, or entry points are named. Start by checking Firecracker's block-device configuration and existing support for guest discard or fstrim; done means determining whether guest file deletion can reduce host image usage and documenting the required configuration or implementation scope.
