register DeferCleanup(cleanupMachine(machine.ID)) so the created machine and its
associated resources are removed when the test completes.
In `@internal/raw/raw_exec.go`:
- Around line 44-45: Ensure the size validation in the raw disk creation flow
occurs before copyFile creates the destination, or remove filename before
returning the existing oversized-source error. Update the rejection test to
verify the destination is absent, preventing localdisk reconciliation from
accepting a disk with the wrong size.

In `@internal/plugins/volume/localdisk/localdisk.go`:
- Line 101: Validate LocalDiskSpec.Size before creating the disk, rejecting
negative values rather than allowing them to bypass raw.WithSize. Update the
local disk creation flow around the visible size check and add an image-backed
test using Size: -1 that verifies creation is rejected.
In `@internal/raw/raw_exec.go`:
- Line 59: Update the resize error path around os.Truncate in raw execution to
remove filename before returning the truncate error, ensuring a failed resize
does not leave the copied source-sized destination in place. Preserve the
existing error propagation and successful truncation behavior.

Do not remove a destination that this call did not create.
Exec.Create does not require filename to be nonexistent, and localdisk.Apply checks existence separately from Create. If filename already exists, Create(filename, raw.WithSize(0)) returns from validation with err set, then the deferred os.Remove(filename) can delete the existing destination. The caller-side check is not atomic.
Create the disk at an exclusive or temporary path, and remove only a path owned by this invocation.

Confirmed with a test, the suggested solution with the temp path is nonsense. On it.

@brsmnv, thanks for testing this. The temporary-path recommendation was too specific. Please use an approach that preserves an existing destination and removes only a file created by this Exec.Create invocation. I will review the revised implementation.

A local disk volume that sets both
