I know (isolated blabla). :-)

"The package using the 'copy-build-system'" is a better wording? ;-)

I do not know exactly how a derivation is computed and what is used to
compute the hash used in the store. Ok, first I have to do my
homework. :-)
But one does not want to hash several tens of GB.

Whatever, I just have the feeling that what you are proposing (with
small tweaks) could improve the situation for "large" data set. I do
not know...


Well, maybe we should work in the same office... it will be easier and
faster than exchanging all these emails and I know yours has an
awesome view :-D
