systemctl show -p Before purge-kernels.service
Before=shutdown.target YaST2-Second-Stage.service multi-user.target YaST2-Firstboot.service
I'm not sure purge-kernels.service:Before=multi-user.target would cause the 'waiting for boot to finish' (actually is it a verbatim message? I can't grep it in sources).
AFAICT it's /usr/lib/systemd/system/plymouth-quit-wait.service
