What do you mean by "most dependencies"?

The code I glanced at in OE-Core seems to indicate it adds all DEPENDS 
from each leaf recipe to the list of targets to build with sstate-cache 
(the same way it's done for OEQA_REPRODUCIBLE_TEST_SSTATE_TARGETS).

Cheers,
Quentin

Same as for Patch 1, what do you mean by "most"?

s/single recipe/recipes/ ? You can have multiple recipes listed there I 
believe?

nitpick: I would say "using sstate-cache for its dependencies" (with a 
link for sstate-cache)

Sadly, DEPENDS is not all the dependencies of a recipe. Some dependencies
are added via
do_task[depends] = "recipe:do_task2"
Those don't appear in DEPENDS but are built anyway.

Look at PACKAGE_DEPENDS for example:
https://git.yoctoproject.org/poky/tree/meta/classes-global/package.bbclass#n232
There are other instances.

I plan to improve the reproducibility test to include all of those with a
suggestion from Richard, and then, going back to the doc and removing this
"most" among other changes...

I can't believe how much I'm learning from reviewing patches for the 
docs. I hope people understand that and we get more people reviewing and 
sending patches to the ML :)

I missed the [depends] thingy and was totally unaware of the other ones. 
Can you then make it explicit which dependencies we're talking about? 
i.e. the ones explicitly listed in DEPENDS (which may not be all 
dependencies, c.f. [depends] varflags, PACKAGE_DEPENDS and other 
implementations).

Thanks for the explanation and pointer, much appreciated!

Cheers,
Quentin

I can't be too explicit since I don't know all of the dependencies and this
should be a non-issue in the next version.
I took your suggestion (I hope that was one ^^) for v4.
