data PackagesPreferenceDefault #

Global policy for all packages to say if we prefer package versions that are already installed locally or if we just prefer the latest available.

Constructors

PreferAllLatest | Always prefer the latest version irrespective of any existing installed version. This is the standard policy for upgrade.
PreferAllOldest | Always prefer the oldest version irrespective of any existing installed version or packages explicitly requested. This is enabled by --prefer-oldest.
PreferAllInstalled | Always prefer the installed versions over ones that would need to be installed. Secondarily, prefer latest versions (eg the latest installed version or if there are none then the latest source version).
PreferLatestForSelected | Prefer the latest version for packages that are explicitly requested but prefers the installed version for any other packages. This is the standard policy for install.
