<dsfdsf>civodul: guix prefetch is nearly ready; thinking of a reliable way to test it; any ideas?
<dsfdsf>it could look like this: we check that the derivation inputs are not present in the store before running prefetch, run prefetch, check again.
<dsfdsf>but there is a problem; if we use 'hello' there aren't many inputs, and most of them are essential (users wouldn't be happy if we remove something like glibc from the store). do you see a workaround?
<dsfdsf>I assume we could create a bogus derivation, for testing purposes. wdyt?
<dsfdsf>but if it works for a simple DAG, it doesn't mean it works for a complicated one. not sure how to address this.
<mark_weaver>you could build a new guix with a different --prefix and store directory, so you start from scratch, and see what happens when you prefetch to build hello.
<mark_weaver>civodul: I posted the patch back in February, subject "[PATCH] gnu: gnutls: Configure location of system-wide trust store", and Andreas wasn't in favor of it, but I didn't get the impression that he was blocking it exactly.
