Yocto Kirkstone - systemd_create_users issue on first build - embedded-linux

Question

I'm building yocto kirkstone for the first time (previously built dunfell) for the boundary devices imx8mm. All the recipes build fine, but late in the rootfs process, I get the following errors in log.do_rootfs.xxx :

I haven't modified the systemd_create_users() function, and the *.conf files from which it pulls users have not been modified by me. I also cannot find any reference to SYSLOG_SU_ENAB, which seems to be the crux of the issue here.
Any thoughts?

Answer 1

I solved this. While it's not clear what happened exactly, it seems I had user-creation and modification entries in multiple recipes. I removed all of these and it built successfully.
Then I re-added the USERADD_PARAM and GROUPADD_PARAM definitions to one recipe and it also built successfully.
I then moved the EXTRA_USERS_PARAMS to the layer configuration, which is where this must be implemented.
