Graph an operating-system derivation

[David Craven]

Hi,

I'm trying to view the graph of an entire operating-system. I don't
know yet if it's too complicated to actually produce something useful
:)

This is what I tried:

guix graph -e '((@ (gnu system) operating-system-derivation) ((@ (guix
scripts system) read-operating-system)
"gnu/system/examples/bare-bones.tmpl"))'

But it fails with "doesn't evaluate to a package". Is there a simple
way to do this / a feature that's generally useful?

Thanks,
David
