NB: in Ganeti 2.8, the ``cmdlib.py`` file was split into a series of files
contained in the ``cmdlib`` directory. If Ganeti is installed from sources
and not from a package, while downgrading Ganeti to a pre-2.8
version it is important to remember to remove the ``cmdlib`` directory
from the directory containing the Ganeti python files (which usually is
``${PREFIX}/lib/python${VERSION}/dist-packages/ganeti``).
A simpler upgrade/downgrade procedure will be made available in future
versions of Ganeti.
