General summary/comments (optional)

It looks like currently stack dot doesn't show dependencies of GHC boot libraries even when such a library comes from a Stackage LTS snapshot. Either the code should be improved by including those dependencies or it should be documented that stack doesn't track dependencies of GHC boot packages.

Steps to reproduce

In the root of the stack repository run stack dot --external | grep '"process"'

Expected

Dependencies of the process package will get shown (e.g. directory or filepath) besides the packages which depend on process.

Actual

Current output (both for versions 1.7.1 and prerelese 1.9.0.1):

{rank=max; "process"; };
"Cabal" -> "process";
"cmdargs" -> "process";
"conduit-extra" -> "process";
"echo" -> "process";
"extra" -> "process";
"githash" -> "process";
"gitrev" -> "process";
"open-browser" -> "process";
"optparse-applicative" -> "process";
"rio" -> "process";
"stack" -> "process";
"streaming-commons" -> "process";
"typed-process" -> "process";
"unliftio" -> "process";
"x509-system" -> "process";

Stack version
