Hi Amos, thanks! I've been thinking about those scripts, let me
summarize my thoughts:
* If we are going to make this using scripts, then we should try as
much as possible to be distro agnostic.
* We could detect services present on guest first before trying to
disable them, ie, instead of just issuing a service koan stop, verify
if there's a /etc/init.d/koan first.
* Have you considered doing this env setup using shell commands typed
on an ssh session, such as
session = vm.wait_for_login()
session.cmd('service auditd stop')
Rather than a script? It's one less script to maintain under the
scripts/ directory.
* Your approach is a blacklist of services that will be turned off.
What if we used a 'whitelist' approach and kept a list of the
fundamental services needed and turn off *everything else*?
Please let me know what you think about this. I'm not applying this for now.
