Thanks! I'm still not quite there, but the suggestion below have been 
quite helpful in my thinking and experimentation.

I think I have an answer for the OS config: pass the --profile option to 
guix package, so the guix package command becomes 'guix package 
--profile=/var/guix/profiles/system/profile -I'

Yes, I did want to inputs in the list as well. However, I worry that 
calculating these by passing package names to the current guix may 
inadvertently list newer inputs than were used by the, potentially older, 
guix that instantiated the profile.

Best,
