Is it really gone, or are they simply not creating the rc.local file any longer?
The file is really gone. You have to create it at the right location.
The documentation is inconsistent. Some say /etc/rc.local, some /etc/rc.d/rc.local. The latter is correct.
What I did:
(1) Create /etc/rc.d/rc.local (with bash shebang), put in the execute commands needed, made it executable for user und group root (but just user root should be ok).
(2) Executed /usr/lib/systemd/system-generators/systemd-rc-local-generator
Is not on the path, you have to enter the complete path yourself - great. This step is indispensable!
(3) Reboot, voila the included programs got started.
I think, this is a better way than to hide the execute commands in user root’s crontab.
Thanks for all the support!
