Thanks for tackling this. I think its worth the effort.

Yes, thats a good minimum requirement. For standalone builds or for small  
devices it
would be even better if it's possible to build everything that might be  
useful in
this setting without a single doc.

It seems to only happen if i have "PLTCOLLECTS=:", not if it's set to  
anything else to unset.
Then a "raco pkg" is enough to trigger it.

Exactly what i was looking for (raco pkg show -a -d). Thanks.

That works as supposed.

Yes, that's what i had in mind because I'm used to this behavior and i was
wondering why raco downloaded the files over and over on a _failed_ install
(Only noticed it because it was a relatively large install). But the  
temporary
files are a good point that i completely forgot. I think, in hope that  
installs
(hopefully) rarely fail it's better as it is now.
