Would there be even more of a performance increase if you just simply
did a "bitbake world" instead of doing all of those targets
sequentially? (I assume "world" builds all recipes and doesn't create
images?)
It appears that all build configurations (on a given slave) use the
same location for DL_DIR and SSTATE_DIR, but the TMPDIR location is
not provided in the configuration file. This would imply each build
uses a fresh TMPDIR directory (since by default it would be set to
${TOPDIR}/tmp which comes from the local.conf)? I'm still trying to
figure out the best/optimal way to be using Yocto at home. When I
first started, I would use a separate directory for each "project"
(i.e. machine, board, architecture, etc). But lately I've realized
that most people just do all their projects in one build location.
However, when switching between different "projects", interspersed
with various "git pulls" in between, I seem to get in a state when I'm
forced to delete my entire TMPDIR location in order for anything to
build cleanly again. Is this the general consensus?
