rc.6 and rc.local_shutdown


Hi,

I'm installing postgresql from slackbuilds.org.

The README-file says that one should put the following lines into /etc/rc.local_shutdown
Code:
# Stop postgres
	if [ -x /etc/rc.d/rc.postgresql ]; then
		/etc/rc.d/rc.postgresql stop
	fi
Since we don't have this file /etc/rc.d/rc.local_shutdown in Slackware I examinded the /etc/rc.d/rc.6 file in order to find out if I could put the code which stops the database there. I found the following lines in /etc/rc.d/rc.local_shutdown
Code:
# Run any local shutdown scripts:
if [ -x /etc/rc.d/rc.local_shutdown ]; then
  /etc/rc.d/rc.local_shutdown stop
fi
This seems odd to me. I think that the script rc.local_shutdown should be called without a parameter (without stop), like rc.local?

I suppose that "stop" doesn't do anything, but probably it should be removed.

I've now created a rc.local_shutdown and removed the stop from rc.6

If nothing makes reference to $1 in the shutdown script then it's not doing any harm, but yes, passing 'stop' to a shutdown script does seem a little redundant.

I've read this on Twitter, but I'll use the database only at home for learning.

Yes, it doesn't any harm, but I wanted to verify that I make no mistake when I delete "stop".

I suspect the only reason the 'stop' is there is because that section of code was a cut/paste from one of the ones above it. I wouldn't worry.

It calls it with $1 == stop because

1) it doesn't hurt
2) if you only have one shutdown script that you're calling, you could actually make a symlink rc.local_shutdown -> rc.postgresql and be good to go.

Thanks Pat, I'll create a symlink.

I missed the point that the "stop" works on a symlink like
Code:
/etc/rc.d/rc.postgresql stop

Sneaky. I would have never thought of that.
I like it.
