On Wed, May 23, 2007 at 10:42:49AM -0400, Matt Hyclak enlightened us:
> I just shared this with Michael on IRC and he suggested I posted it to the
> list, so here it is.
>
> Running koan on a target machine seemed too cumbersome sometimes, so I wrote
> this little app to more or less flip the netboot_enabled bit on a system, so
> that you could run this utility:
>
> cobbler_change_netboot.py enable mysystem
>
> and simply reboot the target machine.
>
> The next logical step, then, is to have the system phone home when it is
> finished reinstalling to flip the bit back to 0. I've done this in the past
> (on a homegrown system) by having the target wget a webpage which was a
> script that changed the status from 'reinstall' to 'installed'. This could
> also be done via some ssh magic.
>
> I would also like to add in some sort of trigger ability much like cobbler
> has to do things like 'puppetca --clean hostname' when preparing for a
> reinstall.
>
> This is a very basic proof of concept of the idea, but to be a good "release
> early, release often" type guy, here it is.

This time with an attachment...
