debugged further into fadd_acl, this calls acl_set_fd libacl/acl_set_fd.c:47, and this calls:
fsetxattr (filedes=filedes@entry=3, name=name@entry=0xaaaaaaab6958 "system.posix_acl_access", value=value@entry=0xaaaaaaacbc00, size=<optimized out>, flags=flags@entry=0)
..which returns -1 and errno = 38 (ENOSYS 38 Function not implemented)
this also occurs on a non-ZFS file system (e.g. ext4).
