There is a FK from base to installers(name) - that makes it impossibe to derive a DB installer from a FS installer; though I'd rather address that with some rake task or similar to load installers easily into the DB rather than try to represent FS installers in the DB, too.

IOW, we might ship files for a Redhat installer, and then load that into the DB during Razor setup, rather than try using the files in the FS.
