OK, so i was doing things right, i just wanted to make sure there is nothing else in play.
And why I asked in first place is because of an error i am getting.
While sysctl start/stop are working just fine, disable returns this:
Synchronizing state for spiceproxy.service with sysvinit using update-rc.d...
Executing /usr/sbin/update-rc.d spiceproxy defaults
insserv: Service pveproxy has to be enabled to start service spiceproxy
insserv: exiting now!
update-rc.d: error: insserv rejected the script header
*** Error in `systemctl': double free or corruption (fasttop): 0x00005573746dbc10 ***
Aborted
pveproxy is enabled and running
Please advise...thanks!
