[sysvinit] Problem with disabling sysvinit service

[sysvinit] Problem with disabling sysvinit service

Dear All,

Maybe here I would find answer to question which puzzles me from some
time.

The problem:

Disable syslog service on startup of sysvinit based board.
(syslog is defined in e.g. /etc/rc5.d/S20syslog -> /etc/init.d/syslog)

Syslog on my setup is provided by busybox.

I was trying to find where 'update-rc.d ... syslog ...' is called in the
poky (2.1.2) source tree but without any success.

Then, I've discovered that it is appended to INITSCRIPT_NAME variable
and further processed by update-rc.d.bbclass


Is there any method/recipe which would allow just removing S20klogd
symlink from /etc/rcX.d from the created rootfs?

The goal is to have syslog installed (in this case built into busybox),
but disabled at boot up time.

Any help is more than welcome.

Tanks in advance,
Łukasz Majewski

You should be able to modify (append) the busybox recipe to not create the
symlinks in the first place. I'm not 100% sure what the correct line is
but INITSCRIPT_PARAMS is the variable you want to modify. Maybe something
like this?

INITSCRIPT_PARAMS_${PN}-syslog = "start 80 . stop 20 0 1 6 ."

(that should be the default except with all start runlevels removed)

Thanks for advice. 

I've also thought about extending image.bbclass
to put function between do_rootfs and do_build.

In this way I could run update-rc.d in it.

Anyway, I will test your solution.

Thanks and best regards,
