Warning:
--------

The setcap binary was not found. This means the tools to set the

will need to run these commands as root or install libcap-2.

Advice:
-------

If you wish to have a non root user to use the lxc tools,
you can add the needed capabilities to the tools by invoking
the 'lxc-setcap' script. To remove the capabilities, use
'lxc-setcap -d'.
