when newidmap is not installed the code would hit the reexec_in_user_namespace_wait code and wait for the child process to be terminated. The child process is blocked waiting on the w pipe. So make sure to unblock the child process first and then clean it up. Closes: containers#7776 Signed-off-by: Giuseppe Scrivano <[email protected]> (cherry picked from commit 7147c93)
