Description

Issue: 
Busybox klogd systemd unit file included in image even if Busybox klogd is not. 

Steps to reproduce: 
Configure with option --with-init=systemd 
Remove CONFIG_KLOGD from the Busybox configuration. 
ie make -C build busybox.menuconfig and set to =n 
Build. Boot the board and check the boot log, or see full log in: 
journalctl --no-pager --full --all | grep klogd 


Result: 
Dec 12 10:11:39 epb2 systemd[388]: Failed at step EXEC spawning /sbin/klogd: No such file or directory 
Dec 12 10:11:40 epb2 systemd[1]: busybox-klogd.service: main process exited, code=exited, status=203/EXEC 
Dec 12 10:11:40 epb2 systemd[1]: Unit busybox-klogd.service entered failed state.. 

Additional info: 
Even if fixed, see below, you still get (this is with 
CONFIG_SYSLOGD but without CONFIG_KLOGD): 
2014-12-10T14:58:26+0000 epb2 systemd[1]: Cannot add dependency job for unit busybox-klogd.service, ignoring: Unit busybox-klogd.service failed to load: No such file or directory. See system logs and 'systemctl status busybox-klogd.service' for details. 

Analysis: 
Existing OpenEmbedded patch not in WRL6: 
http://cgit.openembedded.org/openembedded-core/commit/?id=b44e291a87539fbb8e6da1a16c56f425a417e7bd 
My impression is that the second log entry is generated by (in meta/recipes-core/busybox/files/busybox-syslog.service.in): 
[Unit] 
Wants=busybox-klogd.service 
This second log entry makes it look like busybox-klogd has failed to start even if it has not. 

Workaround

systemd[1]: Cannot add dependency job for unit busybox-klogd.service, ignoring: Unit busybox-klogd.service failed to load: No such file or directory. See system logs and 'systemctl status busybox-klogd.service' for details. 

In order to remove above warning, you should remove CONFIG_SYSLOGD from the Busybox configuration and comment out below two declare in oe-core/meta/recipes-core/busybox/busybox.inc.

-SYSTEMD_PACKAGES = "${PN}-syslog"
-SYSTEMD_SERVICE_${PN}-syslog = "busybox-syslog.service"
