AFAIK all the collision issues are mostly fixed on oe-core master. For me there are still sporadic failures with the SPDX bbclass. Can this change be optional? with something like: TMPDIRAPPEND ?= "-k3r5" TMPDIR:append = "${TMPDIRAPPEND}" This adds the possibility of more easily reverting this change to being able to fix what is pending in oe-core master.
