Hi Florian Pelz,
https://guix.gnu.org/manual/en/html_node/Channels-with-Substitutes.html
Yes, I'm aware about this feature. It doesn't help.
it might be bad timing.
I think this possibility can be excluded because of: 1) I have performed 'guix pull' on the system B for the last few months (maybe half a year) a few dozens of times and every time I observed it build all the derivations by itself. 2) I had performed the experiment. I queried [1] for the latest commit with substitutes and performed 'guix pull --commit="obtained commit"' on systems A and B (they are both x86_64). The results of this experiment are presented in my first message. 3) Today I have preformed the similar experiment. According to [1] the latest commit with substitutes was "5a624adfd". Again, the system B have built all the derivations by itself while the system A have downloaded substitutes.

Hello Nigko Yerden. You could definitely test if substitutes are never available if you used https://guix.gnu.org/manual/en/html_node/Channels-with-Substitutes.html which should guarantee that it will use a version of Guix where guix pull has substitutes. When not using channel-with-substitutes-available, it might be bad timing. Regards, Florian
