I have a file
/etc/init/boinc-client.override with the single line
manual that I use to prevent the BOINC client from starting up. (I don't want it hogging CPU time away from Folding@Home, for now anyway.)
But, after restarting, I noticed that BOINC had started itself up again.
I am sure that, I have upstart installed.
What should I do?
