Series | [v2] rng-tools: Replace obsolete "wants systemd-udev-settle" | expand |
It seems that this change introduced a boot delay for qemux86-64 + systemd build. Steps: git clone git://git.yoctoproject.org/poky . poky/oe-init-build-env add to conf/local.conf: DISTRO_FEATURES:remove = " sysvinit" DISTRO_FEATURES:append = " systemd" VIRTUAL-RUNTIME_init_manager = "systemd" DISTRO_FEATURES_BACKFILL_CONSIDERED = "" bitbake core-image-full-cmdline Cause of boot delay: [ TIME ] Timed out waiting for device /dev/hwrng. [DEPEND] Dependency failed for Hard…e RNG Entropy Gatherer Daemon.
