+Subject: machine: enter target PID namespace when adding a live mount
+
+machinectl fails since 21935150a0c42b91a322105f6a9129116bfc8e2e as it's now
+mounting onto a file descriptor in a target namespace, without joining the
+target's PID namespace.
+Note that it's not enough to setns CLONE_NEWPID, but a double-fork is required
+as well, as implemented by namespace_fork().
+
+Add a test case to TEST-13-NSPAWN to cover this use case.
+
+(cherry picked from commit 98f654fdeab1e1b6df2be76e29e4ccbb6624898d)
