[SOLVED] init.d kill script help please

aus9 · 01-25-2017, 06:12 PM

Hi

I am on MX distro that does not use systemd but still on traditional init

I have read
https://www.behnke.io/fedora-17-on-a...t-on-shutdown/

and attempted to modify it for MX so it reads

Quote:

#! /bin/bash

### BEGIN INIT INFO
# Provides: haltusbpower
# Required-Start:
# Required-Stop:
# Default-Start: 0
# Default-Stop: 5 6
# Short-Description: Halt USB Powersave mode
# Description: A script to halt usb power control.
### END INIT INFO

# Bus list for the runtime power management module.
buslist="usb"

# See how we were called.
case "$1" in
start)
echo "USB bug fix active"
#no-op on startup
;;
stop)
echo "Turning off USB Power Control"
for bus in $buslist; do
for i in /sys/bus/$bus/devices/*/power/control; do
echo on > $i
done
done
;;
*)
echo "Usage: /etc/init.d/haltusbpower {start|stop}"
exit 1
;;
esac
exit 0

in various attempts of using either chkconfig or update-rc.d or insserv
I got various errors including the reason for the current start stop script stuff above

Code:

chkconfig --add haltusbpower
insserv: warning: current start runlevel(s) (0) of script `haltusbpower' overrides LSB defaults (S).
insserv: warning: current stop runlevel(s) (5 6) of script `haltusbpower' overrides LSB defaults (0 6).
haltusbpower              0:on   1:off  2:off  3:off  4:off  5:off  6:off

In particular I thought I should be using 0 for the default stop but when I did
I still do not get a sym link to rc0.d as a kill script

so far they are are all start scripts

Code:

ls -al /etc/rc0.d/ | grep usb
lrwxrwxrwx   1 root root    22 Jan 26 07:56 S01haltusbpower -> ../init.d/haltusbpower

in running as root powers sysv-rc-conf
I have a check against run level 0

if at haltusbpower I press the symbol to start or stop the service
I get the respective echo message....suggesting the start or stop service is working correctly.....manually

#####################################
what I don't have is the correct script to act on shut down as a kill script

any suggestions?

in some attempts insserv has shown sym links

/etc/init.d/.depend.start and its .stop both show haltusbpower

I was expecting to see it only in .depend.stop

thanks for reading

You might want to look at other /etc/init.d scripts on your MX for how they do it (not all init scripts are done the same way on different distros and/or even major releases of distros).

One thing that stands out to me in what you posted:
# Default-Start: 0
# Default-Stop: 5 6

Since 0 is shutdown and 6 is reboot I'd think you'd want to do the stop in those run levels.

You'd likely want to do the start in run levels 2,3,4,5.

If you modify your setting in init script changing those 2 lines and rerun chkconfig commands does it make the links?

By the way you CAN simply do your own links with "ln -s" specifying source and target.

yes I looked at the halt script which had only this header
# Required-Start:
# Required-Stop:
# Default-Start:
# Default-Stop: 0

runlevel 0 me thinks is the shutdown as per
https://wiki.debian.org/RunLevel

but I see you are saying that the script for the normal user who starts a graphical boot up should have that script start up.

interestingly to me, I modified my header to read

# chkconfig: 0 99 1

### BEGIN INIT INFO
# Provides: haltusbpower
# Required-Start:
# Required-Stop:
# Default-Start:
# Default-Stop: 0

then with root powers

Code:

chkconfig --add haltusbpower
insserv: warning: current start runlevel(s) (5) of script `haltusbpower' overrides LSB defaults (empty).
insserv: warning: current stop runlevel(s) (0 6) of script `haltusbpower' overrides LSB defaults (0).
haltusbpower              0:off  1:off  2:off  3:off  4:off  5:on   6:off

then changed header to read

Quote:

# chkconfig: 0 99 1

### BEGIN INIT INFO
# Provides: haltusbpower
# Required-Start:
# Required-Stop:
# Default-Start: 5
# Default-Stop: 0 6

then as already root

Code:

chkconfig --add haltusbpower
haltusbpower              0:off  1:off  2:off  3:off  4:off  5:on   6:off

the dot files /etc/init.d/ .depend.start and .depend.stop show haltusbpower is in there

and

the sym links in /etc...rc5.d..rc6.d..rc0.d are there.

I can't mark this as solved at the moment as it was for another MX user, and that user will need to see if it works

but many thanks for now

I think you need remove the links that were previously installed. You can do that by running the following:

Code:

# update-rc.d haltusbpower remove
# update-rc.d haltusbpower defaults

I don't have checkconfig installed to try but I guess --del serves the same purpose.

Yes sorry, I misspoke, 0 is indeed shutdown and I've edited my original post. Glad you caught that I was saying both of those meant it was going down so should be the "stop" levels in your init scripts. Single user by the way is run level 1 - usually a lot less is started in run level 1 as the reason you're doing that run level is to fix things which is why I suggested you could do run levels 2,3,4 & 5 for the start. Doing the start in just one of those run levels is fine.

member has solved it by editting the halt script and following the advice as shown here
