Hi Raj

I used add the above code in meta/recipes-extended/images/core-image-full-cmdline.bb to
build image with systemd, but still get the same result - get no systemd installed in rootfs image and
system use "INIT" as usual as follows:

$ runqemu qemuarm64
...

root at qemuarm64:~# systemctl
-sh: systemctl: command not found
root at qemuarm64:~#
root at qemuarm64:~# ps aux | grep init
root         1  5.1  0.2   1764  1176 ?        Ss   01:57   0:04 init [5]

Regards,

Jin
