Thanks for the test.
We should be able to use it regardless of whether
the feature is added to cp or ln. However, please
arrange to clean up (unmount) not just on normal
completion, but also when e.g., interrupted.
Note how that is done in the other tests
that mount/unmount file systems. Here's one example:
cp/cp-a-selinux:cleanup_() { cd /; umount "$cwd/mnt"; }

Thanks!
I've added a test for this, too:
