well, both point of views are reasonable. they just make different tradeoffs.

i think an abstraction is missing here, let's call it guix log for this mail. it's something like the git log, but one that lists the buildable and substitutable states of the guix repo.

it's probably the same thing that causes the discrepancy between git commits and substitutes: the build servers are not building every commit of the git repo. they pick an unpredictable (?) series of commits, skipping some inbetween. if i guix pull, or guix time-machine to the "wrong" commit, then i'll need to build some stuff locally. sometimes these can be heavy packages.

this hypothetical 'guix log' is probably also what's missing between a hypothetical staging branch and master, whose role would be to make sure that commits don't reach the users prior to having substitutes for them.

does this make sense?
