It probably isn't worth putting much effort into saving space on the VM code since it is what, 1-2MB? Compare that to a likely 50-100MB for an image with Seaside etc. In the far distant past we used to have to worry about out image sizes but these days they're not really much bigger than the other kind of image that our cellphone cameras produce!

I'm really not up to speed with containers stuff but I'm pretty sure you can configure being able to write to (some) parts of the filing system of your choice.  Anyone out there with better knowledge of this stuff should please chime in, pointers to *good* explanations, tutorials, manuals, doc all appreciated. Googling gets far too much dross these days unless you already know a fair bit.
