Commit ae68cad7 introduced a regression that
makes lxc-attach ignore the exit status of the executed command. This was first
identified in 3.0.4 LTS, while it worked on 3.0.3.

  # lxc-attach --version
  3.0.4
  # lxc-attach -n test false; echo $?
  0

When pure cgroup unified mode is used we cannot pre-mount a tmpfs as this
confuses systemd.
Users should also set lxc.mount.auto = cgroup:force to ensure that systemd in
the container and on the host use identical cgroup layouts.

``/proc`` might be mounted with ``hidepid=2``.
This makes ``/proc/1/…`` appear absent for non-root users.
When using the templates or the nvidia hook as a non-root user
(e.g., when creating unprivileged containers) the error
"/proc/1/uid_map: No such file or directory" is printed.
Since the script works correctly despite the error, this error
message might be confusing for users.

If SSL is enabled, utils will include function `do_sha1_hash()` to
generate a sha1 encrypted buffer. Last function argument of
`EVP_DigestFinal_ex()` requires a `unsigned int` but the current
parameter is an `integer` type.

Most kernels don't have this functionality yet, and so the warning is
printed a lot. Our people are scared of warnings, so let's make it INFO
instead in this case.

Suggested usage:

	return error_log_errno(err, "Failed: %s", "some error");

It sets errno to the value of err, then calls SYSERROR with the format and remaining args.

It always returns -1.
