> I'd like to tie in to jclouds's TemplateBuilder so that I can use its
> filtering/matching capabilities but then use custom logic to determine which
> of the matching images is "best" (for my custom value of best, i.e.
> preferred).
> The driving use case is that I want a portable way to say "any recent ubuntu
> or centos". Normally this is the default of course but it doesn't always do
> the right thing when other options are specified -- broken ubuntu "alpha"
> images in AWS being the worst offender (asking for 16gb RAM in us-west-1
> gives back an awful ubuntu 8.04 alpha, for instance!). It would also handle
> use cases where someone wants to say "Ubuntu 11 or 12, or CentOS 6.x, is
> best. failing that, Ubuntu 10 or CentOS 5.x. (and never any alpha images!)".
> I'm thinking allowing to set an `imageSorter(Ordering)`. This fits with how
> the TemplateBuilderImpl currently works (it already uses an Ordering, you
> just can't change it; and it stays in line with the naming convention of
> `Sorter` as in `Ordering hardwareSorter()`.)
