/sbin/reboot doesn't run /etc/init.d/rcK

Description
My inittab has this:
# Stuff to do for the 3-finger salute
::ctrlaltdel:/sbin/reboot
# Stuff to do before rebooting
::ctrlaltdel:/etc/init.d/rcK
::ctrlaltdel:/bin/umount -a -r
::ctrlaltdel:/sbin/swapoff -a
But the rcK script, which runs the "stop" function of all init scripts, is not getting run when /sbin/reboot is called.
To get around this I can do the following:
- Create a postbuild script in Buildroot
- If /sbin/reboot.bin does not exist but /sbin/reboot does,
cp /sbin/reboot /sbin/reboot.bin
create /sbin/reboot.sh to call rcK && /sbin/reboot.bin
ln -s /sbin/reboot.sh /sbin/reboot
- % Done changed from 0 to 30
I looked at the init code in Busybox. SHUTDOWN is the correct event to recognize, but only a SIGTERM actually causes the SHUTDOWN events to be processed. reboot issues a SIGINT.
So the way around this is to have a postinstall script in the Buildroot build that removes /sbin/reboot and replaces it with the following script:
#!/bin/sh
kill -15 1
I should check on the Busybox list as to my interpretation here. Maybe I missed something. But it seems like /sbin/reboot should cause SIGTERM and not SIGINIT if you want to be able to run SHUTDOWN events in init.
- Status changed from New to Resolved
- % Done changed from 30 to 100
For reasons not yet clear, this issue has cleared up on the latest build. It was mostly likely caused by a combination of issues related to how I modified the run time including inittab.
For now, the issue is resolved. We'll return to it again if it shows up again.
- Status changed from Resolved to Closed
Retried this today. /sbin/reboot does, indeed, run rcK. Not sure what the original problem was, but it's not there now.
Closing this issue.
