* Revert "conf: remove extra MS_BIND with sysfs:mixed"
    This should let privileged Ubuntu 14.04 containers boot
    again.

* conf: use SYSERROR on lxc_write_to_file errors
    Slightly more useful error output in a specific error
    case.

Subject: [PATCH] Revert "conf: remove extra MS_BIND with sysfs:mixed"
This reverts commit 51a922baf724689ff3a0df938ca8975601c9c815.
The above commit confuses the mountall unit of privileged
Ubuntu 14.04 containers at startup so that they cannot
finish booting.
