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 service
VIRTUAL-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

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