Here is what I found: The version of vfs_syscalls.c on that repository is 3
years old and does not support CLONE_ACL. Still it should provide a good idea
about the implementation before this flags was introduced.
https://github.com/apple/darwin-xnu/blob/2ff845c2e033bd0ff64b5b6aa6063a1f8f65aa32/bsd/vfs/vfs_syscalls.c#L8201
if (uap->flags & ~(CLONE_NOFOLLOW | CLONE_NOOWNERCOPY)) {
return EINVAL;
}
I was able to run my sample on macOS 13 recovery environment. The CLONE_ACL
flag is supported there. I don’t see any difference in the final result with or
without the flag. Both clones have UNIX permissions, extended attributes and
time stamp from the source.

I tried running cp with your patch there, but it depends on a dynamic library
and fails to run. My attempt to use chroot failed, probably due to file
signatures: Killed 9.
