I've just got two comments about get_curdir_fd:
- when using readlink, please make sure the returned string is
  NUL-terminated, see e.g. getfdpath_pid;
- the most likely reason why readlink of /proc/self/cwd could fail is that
  /proc is not mounted, let's use perror_msg_and_skip instead of
  perror_msg_and_fail in that case.
