I see that Guix is requesting substitutes from the build servers beforeit builds a profile derivation.

Can you show more precisely what you mean by pasting a command and itsoutput?
With the recent changes in the implementation of grafts, what happens isusually this:
$ guix build foo updating the list of substitutes… The following things will be built/downloaded: …
updating the list of substitutes… The following things will be built/downloaded: …
The second stage here typically includes profile.drv as well as grafts.All this is expected behavior.
Detailed behavior depends on what’s in /gnu/store, the freshness ofsubstitute info in /var/guix/substitute/cache, and applicable grafts forthe package(s) at hand.
Thanks,Ludo’.

All this is expected behavior.
I think that since profile.drv is always produced locally on themachine, then it's unnecessary to update the list of substituteswhen it's on that second stage.

I don’t observe this, or rather I cannot blame profile.drv for this.
Can you show more precisely what you mean by pasting a command and itsoutput?

So it seems it tries to look for substitutes when the profile hooks are built,not when profile.drv is built.
Here is the output without build hooks:```itsme@antelope ~> guix environment --ad-hoc helloThe following derivation will be built: /gnu/store/gkz9hzjpc9pj1np7vi5pwb4xhmssk55d-profile.drvbuilding profile with 1 package...Welcome to fish, the friendly interactive shellitsme@antelope ~ [Guix env: /gnu/store/nsi48y..]>```
And here is output with build hooks:```itsme@antelope ~> guix environment --ad-hoc man-db hellosubstitute: updating substitutes from 'https://berlin.guixsd.org'... 100.0%substitute: updating substitutes from 'https://mirror.hydra.gnu.org'... 100.0%substitute: updating substitutes from 'https://ci.guix.gnu.org'... 100.0%The following derivation will be built: /gnu/store/w623j5spid7kyxjdp6xbgxs2r5scpjkn-profile.drvThe following profile hooks will be built: /gnu/store/14d1mgn1mwz66mj28rwjmnkddskf4zm0-info-dir.drv /gnu/store/7rrkqrdpxahk8g0927d56lpgz3n1kl6z-manual-database.drv /gnu/store/8h76m85hiyilv0mj053i9n7k2nxb0wf1-ca-certificate-bundle.drv /gnu/store/ia5d18hpmza375dizljqi2x12zlirwqi-fonts-dir.drvbuilding CA certificate bundle...building fonts directory...building directory of Info manuals...building database for manual pages...building profile with 2 packages...Welcome to fish, the friendly interactive shellitsme@antelope ~ [Guix env: /gnu/store/9qv380..]>```

Looks like manual-database.drv was the only hook not mark asnon-substitutable.
Fixed in 69de98391d720b92206d5e45072ecd3944d95774.
