hotplug problem

hotplug problem

[bgerard]

Hi

I'm working on an embeded system with linux kernel 2.4.27 and busybox 
1.00. Lately I've decided to add hotplug feature to my kernel in order 
to automaticaly mount usb keys.

When I plug the usb key, I can see in the kernel debug that 
"/sbin/hotplug" is called but my script is not executed. I've tried to 
replace the hotplug script by a simple one but nothing appeared. Here is 
my script :
#!/bin/sh
echo "usb key un/plugged"

The script is working when I run it myself (./sbin/hotplug )

I've also noticed that when kmod try to call modprobe, it's not executed 
while the debug message says that everything went fine.

Can anyone help me ?
Thanks in advance.
Ben.

I don't know much about hotplugging on 2.4.x and how you might need
to enable it in /proc... it just works for me on 2.6. with
CONFIG_HOTPLUG enabled and the latest hotplug-scripts.

Try newer modutils?

And you might have more luck asking on:
linux-hotplug-devel@lists.sourceforge.net

Hotplug is well enabled in /proc/sys/kernel/hotplug, I specified in it 
the path of /sbin/hotplug and according to the documentation that's all 
I need to do to configure hotplug.

I don't think modutils is responsible for that, I think the kernel can't 
call program in the user space and I don't kwnow why

Thank you for your quick answer
