If only "the right thing" worked in all cases.
FWIW, my cut at this[*] has cp -a still equivalent to cp -dpPR,
just like rawhide, below.

Do you know what motivated the "mode = acls[1] no" change below?
That introduces a new incompatibility with upstream.
Otherwise, upstream matches rawhide.

[*] I resumed work on my coreutils selinux merge recently, so you should
hear more about it soon -- on the bug-coreutils and bug-gnulib lists.
