update-rd.d remove postopek

Pozdravljeni!

Težave imam pri razumevanju uporabe zgornjega ukaza v raspbianu.

Instaliral sem skripto z uporabo ukaza

sudo nano /etc/init.d/mojaskripta
sudo chmod 755 /etc/init.d/mojaskripta
sudo update-rc.d mojaskriptadefaults

Zdaj bi rad skripto odstranil.pri tem imam težave z ukazom

sudo update-rc.d mojaskripta remove

Tukaj piše:
When invoked with the remove option, update-rc.d removes any links in the /etc/rcrunlevel.d directories to the script /etc/init.d/name. The
script must have been deleted already - update-rc.d checks for this.

Če pravilno razumem to pomeni, da moram najprej izvesti

sudo rm /etc/init.d/mojaskripta

in potem še

sudo update-rc.d mojaskripta remove

?

Če pa uporabim -f switch (-f Force removal of symlinks even if /etc/init.d/name still exists.)

sudo update-rc.d -f mojaskripta remove

pa file /etc/init.d/mojaskripta lahko ostane tam kjer je in še naprej uporabljam

sudo service mojaskripta start|stop

?

Tukaj v točki "1. Removing a Service" piše:
Note: This command will only disable the service until next time the service is upgraded. If you want to make sure the service won't be re-enabled upon upgrade, you should also type the following:
# update-rc.d apache2 stop 80 0 1 2 3 4 5 6 .


Ali moram res izvesti še kakšen dodatni ukaz?

Ustaviti že, ne razumem dela, ki pravi:
When invoked with the remove option,

sudo update-rc.d mojaskripta remove

update-rc.d removes any links in the /etc/rcrunlevel.d directories to the script /etc/init.d/name. The script must have been deleted already - update-rc.d checks for this.

to pomeni, da moram najprej izbristi skripto?
