In `man fs_snapshot_create` is stated "All snapshot functions require superuser privileges and also require an additional entitlement."Which entitlement is it?Background:I want to write a tool to create snapshots without `tmutil localsnapshot /` because I noticed that these snapshots are deleted randomly. So I had the idea to check if this only applies to snapshots created with `tmutil` or to APFS-snapshots in general... if it's `tmutil`-related I could circumvent it by using my own app – because for me snapshots are pretty useless if they vanish magically.
