This question already has an answer here:
- Revert to upstart 1 answer
I found this : How can I replace upstart with systemd?
but I would like the other way around.
The reason is that I spend quite a time learning the basic init process and I am pretty much accustomed to the "service" commands. I really dont care about 10 - 20 millisecond or even 1 -2 seconds of late boot up. I just need some clarity in the init process and want to stick to the old system..
Is it possible to do this at the boot time using grub maybe, which blacklists systemd and just runs the 14.04 init routines ( I guess it was a mix of upstart and sysvinit )?
I found something, but dont know how to proceed further:
In the /etc/grub.d/10_linux, I find an entry with
SUPPORTED_INITS="sysvinit:/lib/sysvinit/init systemd:/lib/systemd/systemd upstart:/sbin/upstart"$
