What is the correct/safe way to move from upstart to systemd?
I originally installed upstart in 11.3 and have now upgraded to 11.4. Having successfully upgraded to 11.4 I tried to use yast2 to install systemd and systemd-sysvinit onto my running system. Yast correctly identified that upstart should be deinstalled as a prerequisite for installing systemd-sysvinit.
After the install of systemd the system wouldn’t shut down, and on a reset the system reported many systemctl/start service timeouts on things such as mounts and ttys. Eventually the system started an X-windows KDM login, but there were no console ttys and mounts were missing.
I used X/kdm to login to root - phew! - I restored / from an rsync backup I’d made prior to the changes, so I’m back in business with upstart. I’d like to tidy up and move to systemd - so any info on how to make the move would be appreciated.
I going to have a nose around myself, perhaps I will try switching back to sysv init and then going to systemd - but I have to wait for the machine to be idle before I experiment, any info in the mean time would be great.
