Would that be different from your suggestion that if the curl update caused
a rebuild of too many packages (whatever that would mean, which is a separate
discussion) it should not be done on core-updates, but on its own branch,
for instance, curl-update? One practical advantage I see in a staging
branch, if I understand your suggestion correctly, is that one would not need
to modify the set of jobs on hydra to now also build curl-update, and then
maybe giflib-update, and then xyz-update, but it would always be called
"staging".
Now the "well tested" assumption is dubious. I actually do not know whether
the curl update will go through. I tried to build one of the packages shown
by "guix refresh -l curl" that looked simple (mpd), but it turned out it
was not simple at all and needed a lot of rebuilds (including texlive).
Admittedly, I could have spent more time searching a direct dependency,
probably by using one of your recent graph drawing commands. So in case
a problem turns up, would we revert a curl update on the staging branch
and do more local work before proposing it again?
And if Efraim wished to do a gitlib update after my curl update, what would
be the protocol? Would he be expected to wait until the hydra build of the
curl update has finished? Or at least until it has finished on x86_64?
Otherwise, we would again face the risk of the staging branch becoming
an update-the-world branch with unforeseen ramifications.
