Feature proposal:

We should download image/kernel as soon as the distribution is
created. We should provide a button to re-download image/kernel (very
rarely distros fix issues in images). And we should keep those until
distributions are deleted. Database ID should be enough to make
image/kernel unique enough (while keeping the similar naming pattern:
ID-Distribution_name).

With this approach, we can also add all distributions in the local boot
menu as optional menu entries for network "guests" that needs to
manually install a distribution (e.g. you have a contractor who booted a
new server on the network installing Fedora to do some testing).

Of course this has some drawbacks for example when media path is changed,
then we need to at least warn the user to re-download images and
kernels. But I see these as minor issues - the problems you face are
rather bad.

Ohad if you like this feature, please prioritize it accordingly.
