We decided to use environmental scripts to set up any host specific
prerequisite priour to execution any tests. This way there would be a
standard/preferred way for tests to set up a specific environment on the
host.

I am including a snippet form a previous email explaining why we went
down this path...

'pre_command' and 'post_command' that represent shell commands to be
executed before/after the test. A typical shell command would be one
that runs an environment specific script that sets up mount points or
whatever is needed for the test. This parameter would be provided for
each test (in the config file) so one can 'variant' on it, to make
different variants of the test (e.g. 'dbench' with local storage, and
then with NFS storage, ...). There can also be pre/post-processing
scripts for the entire job, that run before the first test and after the
last one.

kvm-autotest code in order to perform environment specific setup (and
you also limit the user to python). I personally prefer to leave all
environment specific stuff in external scripts outside the code, but I
may be wrong.
