I don't want much...

I don't want much...

[David Greaves]

Hi

This overview page:
  http://linux-hotplug.sourceforge.net/?selected=overview
Says that a "Starting an application" is a reasonable thing to want to do.

I just want to run a script.
A simple script.
That's it.
Why on earth is it so hard?

Hmm, maybe not the best tone to start with - but isn't hotplugging about 
making the user's life easier?
It's cool that it automatically loads my modules.
Now all I have to do is start a shell and type: mount -t vfat -o 
uidÚvid,gid=greaves,sync /dev/sda1 /mnt/lexar
Not exactly plug-and-play is it?

When I plug in my Lexar Jumpshot I want to mount the drive and rsync my 
piccies.
What happens?
I get a usb event
then a scsi-host event
then a scsi event
then a block event
and another block event
then a scsi-device event

Fine.
So I add a usermap tied to the usb vendor/product id (the 'right' place) 
and create a dummy module called lexar.script with a control script.
It runs - good.
At the wring time (ie before the scsi devices are registered) - bad.

Do I really have to hack into the generic scsi-device agent?

It worked well for me with my usb stick, I put the script, called the
same as the entry in the usb.usermap file, in the /etc/hotplug/usb
directory, and it worked well, but I assumed the block device was always
named the same.

What did put in your script ?

Mine follows:

----->8---cut-here---------
#!/bin/bash
logger -t usbbar Mounting...
err_mesg=`/bin/mount /key 2>&1`
if [ "$?" == "0" ]; then
        logger -t usbbar OK 
else
        logger -t usbbar Error: $err_mesg 
fi
----->8---cut-here---------

(BTW, I had an entry in my fstab)

However, my best advice would be to use udev, and not hotplug only, and
to use the dev.d scripts.
