Hi, I don't think so. At the moment we are using rocko release and found this problem in util-linux-2.30 recipe.
the problem is that util-linux builds with regular user permissions and result files are owned by user with uid 1000 in our case. for most of binaries in /bin and /sbin generated by util-linux this permissions issue is not a problem (Because all binaries has o+x set). But for those of them who have suid bit setted it became a real trouble.
