Potential (?) systemd YOCTO problems


Zoran
 

Hello Folks,

I am a bit deeper to the systemd service investigation in YOCTO. I
installed systemd service, I also have network manager package.

I am using warrior. Here are the snippets of the HOST:
[user@fedora29-ssd build]$ bitbake --version
BitBake Build Tool Core version 1.42.0
[user@fedora29-ssd build]$ bitbake -s | grep networkmanager
networkmanager :1.16.0-r0
networkmanager-openvpn :1.8.10-r0
python-networkmanager :2.1-r0
[user@fedora29-ssd build]$ bitbake -s | grep systemd
python-systemd :234-r0
python3-systemd :234-r0
systemd 1:241+AUTOINC+c1f8ff8d0d-r0
systemd-bootchart :233+gitAUTOINC+fe1c5e41e6-r0
systemd-bootconf :1.00-r0
systemd-compat-units :1.0-r29
systemd-conf :241+AUTOINC+c1f8ff8d0d-r0
systemd-machine-units :1.0-r19
systemd-serialgetty :1.0-r5
systemd-systemctl-native :1.0-r6
[user@fedora29-ssd build]$

Still. I expected to see the following on the target (my BBB):
/etc/init.d/networking script, but I have the following:
root@beaglebone:/etc/init.d# pwd
/etc/init.d
root@beaglebone:/etc/init.d# ls -al
drwxr-xr-x 2 root root 4096 Jun 3 2019 .
drwxr-xr-x 27 root root 4096 May 30 23:46 ..
-rwxr-xr-x 1 root root 1419 May 31 2019 socketcand
root@beaglebone:/etc/init.d#

The socketcand recipe is here:
https://github.com/ZoranStojsavljevic/meta-socketcan/blob/master/recipes-can/socketcand/socketcand.bb

Should I add something to the networkmanager recipe (to add some
inheritance)??? To have the component (network script) in
play/installed (in /etc/init.d/)?

The command: # systemctl restart systemd-networkd does work.

root@beaglebone:/etc/systemd# ls
coredump.conf logind.conf networkd.conf sleep.conf
system.conf user
journald.conf network resolved.conf system
timesyncd.conf user.conf
root@beaglebone:/etc/systemd# cd network
root@beaglebone:/etc/systemd/network# ls -al
drwxr-xr-x 2 root root 4096 May 31 00:57 .
drwxr-xr-x 5 root root 4096 Jun 3 2019 ..
root@beaglebone:/etc/systemd/network#

What I am doing wrong here?

Thank you,
Zoran

My understanding is that if the former is set to "sysvinit", it causes any redundant SysVinit scripts to be removed, and further, that if the latter is set to "", then all initscripts are removed from the image altogether.

I would like to thank you for the advice. I tried several combinations
without any success, and at the end I came up exactly what you have
suggested to me.

Local.conf looks something like this:
https://github.com/ZoranStojsavljevic/bbb-yocto/blob/master/experimental/local.conf_core-tools-profile

And the latest changes committed which I have tried following your
suggestion are:
https://github.com/ZoranStojsavljevic/bbb-yocto/commit/83c22e8ec516020206dc1b34e93276cca8f3f16b

I need to do more tests... But seems that initial tests show that all
scripts are in place, and systemd is used.

This also should be much better documented somewhere in YOCTO
documentation. My best guess (I did not find it anywhere in the
manuals, maybe I missed the paragraph - please, advice where it is?).

Thank you again,
Zoran

This is where I found it previously:

Thank you again,
Glad I could help.
