How to check if systemd is correctly setup

How to check if systemd is correctly setup

[Elvis Dowson]

Hi,
      I haven't used systemd before, and I've just built a linux kernel image using the latest yocto poky/master.

The boot process starts as normal, but it just displays "freeing memory (some value)" and I get no console prompt.

Q1: Which config setting or recipe code, controls the inclusion of systemd in the root filesystem?

Q2: How can I check to see if systemd is properly configured for my target (virtex-5-powerpc-405-ml507-softfloat)?

Best regards,

Elvis Dowson

First thing, make sure that your kernel has this in the config:
   CONFIG_DEVTMPFS=y
   CONFIG_DEVTMPFS_MOUNT=y
The latest udev (rev 182) has to have this to work.

Yes, my defconfig has the above two configs set.

Which file control if systemd gets pulled into the core-image-minimal recipe? 

Where are the systemd configuration files stored?

In my kernel boot message, 

devtmpfs: mounted
Freeing unused kernel memory : 168k freed
_

I am able to ping to the board from a terminal console on the host, and I get a reply.

However, I don't see a console prompt, even though on my bootargs i have set init=/bin/sh
