Probably you are missing CONFIG_CGROUPS in your kernel configuration.
Please read README file in the systemd sources folder - it describes all options
required to be enabled in kernel configuration.

> [2] I would like also to include networkctl service (should I do something specific to

Please add following to your conf/local.conf file:
PACKAGECONFIG_append_pn-systemd = " networkd"

Hello Lukasz,

Thank you very much for the advises. I did what you have suggested, and
this does work.

And it solves my basic problem (NO GO for some reason when I had network
manager).

I use DUT (BBB) with YOCTO initramfs linux as testing vehicle for my
various pass-through VBox VMs (several designs) via my notebook host to
test them, how different designs VMs connect and interact with DUT.

Lukasz and Peter,

I also will investigate more about systemd service in order to get more
inside info about how to properly configure the service.

Thank you,
Zoran

can you share how you built your initramfs?  Are you saying that you
are booting an initramfs which then mounts the rootfs where you have
core-image-minimal?

Re: Systemd service recipe fails while booting from initramfs

[Zoran Stojsavljevic]

Hello Nicolas,

I build ONLY initramfs to be used on BBB DUT in order to test VMs. I
do not use mtd neither flash rootfs (as mounted on flash), although in
the BBB DUT's flash I have embedded Debian stretch. I use different
ash scripts in U-Boot to bring only ramboot.

Here is the proof:
root@beaglebone:~# df
Filesystem           1K-blocks      Used Available Use% Mounted on
devtmpfs                213596         0    213596   0% /dev
tmpfs                   251260         0    251260   0% /dev/shm
tmpfs                   251260      8428    242832   3% /run
tmpfs                   251260         0    251260   0% /sys/fs/cgroup
tmpfs                   251260         0    251260   0% /tmp
tmpfs                   251260       116    251144   0% /var/volatile

But this email thread, my best guess, addresses your concerns:
https://lists.yoctoproject.org/pipermail/yocto/2018-July/041680.html

There is also how to build image with initramfs ONLY, in this thread,
written by me:
https://lists.yoctoproject.org/pipermail/yocto/2018-July/041696.html

I hope this helps.

Zoran

Re: Systemd service recipe fails while booting from initramfs

[Peter Bergin]

[-- Attachment #1: Type: text/plain, Size: 7244 bytes --]

Hi Zoran,

I'm not sure I got your question correct but I'll try to give you a 
super simple network config for systemd-networkd using dhcp.

Add the file '/etc/systemd/network/10-dhcp.network' with the following 
content:

     	[Match]
	Name=*

	[Network]
	DHCP=yes

Then I hope you will get your interface up with DHCP.

Regards,
/Peter

Could be that you miss some required kernel configurations. See 
systemd/README 
(https://github.com/systemd/systemd/blob/8464d9e0dc506538fd0f2d1d667966750cb9cf30/README#L38)

PACKAGECONFIG will control which features you have enabled for systemd. 
To check which ones you have you can execute 'bitbake -e systemd | grep 
^PACKAGECONFIG='. If you want to change this config you can adjust 
PACKAGECONFIG in your own systemd_%.bbappend file.

I guess networkd is enabled default with the systemd recipe. But check 
it out. There are several way to see which files that are included in 
your image. I use buildhistory.bbclass in all my build which make it 
easy too look up what's included.

/Peter

Systemd service recipe fails while booting from initramfs

[Zoran Stojsavljevic]

[-- Attachment #1: Type: text/plain, Size: 1757 bytes --]

Hello to all,

I have added to my local.conf the following lines in order to port systemd
service
in YOCTO (Thud release):






*## Add systemd serviceVIRTUAL-RUNTIME_init_manager =
"systemd"VIRTUAL-RUNTIME_dev_manager =
"systemd"DISTRO_FEATURES_BACKFILL_CONSIDERED =
"sysvinit"VIRTUAL-RUNTIME_initscripts = ""DISTRO_FEATURES_append = " nfs
systemd"*

By executing bitbake -k core-image-minimal command, all went good (although
it rebuilt
almost the whole build - circa 80% of it), which is understandable.

While downloading initramfs on the target system, while bringing kernel up,
the following
happened (actual log):
[    0.000000] Kernel command line: console=ttyO0,115200n8 root=/dev/ram0
ip=dhcp
... [snap]...
[  114.064032] Sending DHCP requests ...... timed out!
[  190.652571] IP-Config: Auto-configuration of network failed
[  190.663158] Freeing unused kernel memory: 1024K
[  190.668661] Run /init as init process
System time before build time, advancing clock.


*Failed to mount tmpfs at /sys/fs/cgroup: No such file or directoryFailed
to mount cgroup at /sys/fs/cgroup/systemd: No such file or
directory[!!!!!!] *Failed to mount API filesystems, freezing.
*Freezing execution.*
[  192.984442] random: crng init done

I have two questions (please, could you provide to me some help here):
[1] How to fix this run-time bug (what I should do in the configuration)?
     I found some interesting explanation about possible solution
*(PACKAGECONFIG)*:

https://lists.yoctoproject.org/pipermail/yocto/2013-November/016965.html
[2] I would like also to include networkctl service (should I do something
specific to
     enable it, or this is done by default enabling systemd)?

Thank you,
Zoran
