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.

Dragos

The systemd-udev-settle service is listed as obsolete and does in
some cases result in a significant boot time. Replace that with a
specific wait for the random source hardware device to be loaded.
Before this change:
Startup finished in 4.025s (kernel) + 2min 13.236s (userspace) = 2min
17.262s
multi-user.target reached after 2min 8.153s in userspace
After this change:
Startup finished in 3.956s (kernel) + 13.294s (userspace) = 17.250s
multi-user.target reached after 9.522s in userspace
