Beginning with 21.02 I'm seeing systemd warnings in the console for about eight services (example with openipmi below):
systemd-sysv-generator:"SysV service '/etc/init.d/openipmi' lacks a native systemd unit file. Automatically generating a unit file for compatibility. Please update package to include a native systemd unit file, in order to make it more safe and robust."
Screenshot attached shows them all.
I did a fresh install with the current nightly to see if the warnings remained and they do.
