I had the same fun trying to deal with hotplug scripts.
The stdout is not connected to where you expect so echoes don't appear.
You can do "echo pippo > /tmp/test.txt" and look in the file for the messages
to debug.
I'm sure there's a better way, but that worked for me!

Subject: R: USB flash auto-mounting
Phil,
I'm running git kernel 2.6.25. Following your way I tryed a simpler
arrangement:
# cat /etc/udev/rules.d/99-usb-automount.rules
KERNEL=="ub[a-z]1", RUN+="echo pippo"
Then I plug in the usb stick ...
usb 1-1: new high speed USB device using musb_hdrc and address 2
<6>usb 1-1: configuration #1 chosen from 1 choice
usb 1-1: configuration #1 chosen from 1 choice
<6>usb 1-1: New USB device found, idVendor=1370, idProduct=0324
usb 1-1: New USB device found, idVendor=1370, idProduct=0324
<6>usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
<6>usb 1-1: Product: unitedCONTRAST
usb 1-1: Product: unitedCONTRAST
<6>usb 1-1: Manufacturer: Swissbit
usb 1-1: Manufacturer: Swissbit
<6>usb 1-1: SerialNumber: 000010005690B900008c
usb 1-1: SerialNumber: 000010005690B900008c
<6> uba: uba: uba1 uba1
<6>usbcore: registered new interface driver ub
usbcore: registered new interface driver ub
Nothing more occours, while I expected to see "pippo" label somewhere.
It seems the /etc/udev/rules.d/ automatism is not working.

Oggetto: RE: USB flash auto-mounting
Hi Gabriele,
We have also been round this loop.
You also have the issue that the 'udev' package in the LSP is too old.
With more recent versions you can trigger an arbitrary program to run on both
the plug and unplug events. This does not work in the version that ships with
MV Pro 4.0.1.
For example on a Fedora Core 4 box, I have the following
[EMAIL PROTECTED] udev]# cat rules.d/99-usb-automount.rules
KERNEL=="sd[a-z]1", RUN+="/usr/local/bin/usb_mount",
ENV{REMOVE_CMD}="/usr/local/bin/usb_mount"
Where /usr/local/bin/usb_mount is a script wrapper around mount/umount
as follows...
#!/bin/bash
# $Id$
#
# Script to automaticlly mount usb devices. This script is designed to
work
# with udev
#
#commands used in the script
MOUNT="/bin/mount"
UMOUNT="/bin/umount -l"
MKDIR="/bin/mkdir -p"
RMDIR="/bin/rmdir"
#the root of where all auto mouted devices will be mounted to.
MOUNT_ROOT=/mnt/auto
MNT_POINT=$MOUNT_ROOT/${DEVNAME##/dev/}
logger "running $0"
logger "ACTION=$ACTION ID_BUS=$ID_BUS DEVNAME=$DEVNAME
ID_FS_TYPE=$ID_FS_TYPE"
# check we are adding a usb device
if [ "$ID_BUS" != "usb" ]
then
logger "ignoring non usb device"
exit 0
fi
#check the action to process
case "$ACTION" in
add )
logger "mounting new device"
#create the directory we will mount to
$MKDIR "$MNT_POINT"
#
#mount the usb device with the following options
#
# ro - read only
# noexec - Do not allow direct execution of any binaries
on the mounted file system
# nodev - Do not interpret character or block special
devices on the file system
#
#$MOUNT -t $ID_FS_TYPE $DEVNAME $MNT_POINT -o ro,noexec,nodev
$MOUNT -t $ID_FS_TYPE $DEVNAME $MNT_POINT -o noexec,nodev
#check if mount suceeded
if [ $? -eq 0 ]
then
# sucess, we mounted ok.
logger "mounted $DEVNAME at $MNT_POINT"
else
# we failed to mount so remove the mount point
logger "failed to mount $DEVNAME at $MNT_POINT"
$RMDIR "$MNT_POINT"
fi
;;
remove )
logger "unmounting existing device"
# check if the device is really mounted
#if [ (grep -q "^$DEVNAME" /proc/mounts || grep -q "^$DEVNAME"
/etc/mtab) ]
#then
# logger "$DEVNAME not mouted"
#endif
#unmount the device. We will refer using the mount point not
the device name
#becase there is a posibility the device could be removed
before we
#do the umount.
$UMOUNT "$MNT_POINT"
#remove the mount point
$RMDIR "$MNT_POINT"
logger "unmounted $DEVNAME and removed $MNT_POINT"
;;
* )
logger "ignoring unkown action"
;;
esac
This method works fine on the Fedora Box. Note that the Fedora box is
in runlevel 3, so no GUI or in fact any screen/keyboard.

udev will create the device files but not mount the device (at least
not in our configuration.. I haven't got much into udev and suspect it of
taking a lot of processing power on boot so plan to remove it).
We have custom hotplug scripts to mount the device,
/etc/hotplug/block.agent
you get a load of environment variables and some command line arguments
to determine what to do.
hope that helps

Subject: USB flash auto-mounting
Hi,
I'm wondering if anyone has definitively solved the issue of
having a USB flash
drive automatically mount to the file system when it is
inserted?
To do this manually is quite simple:
mkdir /media/usbflash
mount -t vfat /dev/uba1 /media/usbflash
I wish to make this mount occur automatically every time the
stick is plugged in.
I did check .config to see if "CONFIG_HOTPLUG=y": it is.
In /etc/fstab I put the following line:
none /proc/bus/usb usbfs defaults 0 0
but it is not sufficient.
Tanks a lot
Gabriele
An update on the situation, I?ve gotten the usb flash drive
automounting, but only if I have it plugged in to the unit
during
bootup. I can?t get it to automount using hotplug or anything
else.
The way I have my fstab and udev mounting happening is the
following:
udev/rules.d/99-mount.rules :
BUS=="usb", SYSFS{product}=="JD FIREFLY", KERNEL=="sd?1",
NAME="lexar",
SYMLINK="usbdevices/lexar", RUN+="/usr/local/bin/mountlexar.sh"
fstab:
/dev/sda1 /media/LEXAR vfat
rw,nodiratime,sync,nosuid,nodev,noexec,fmask=0033,dmask=0033 0 0
I think I may have moved around the initialization scripts
within /etc/rc.d/rcS.d to make the mountall script run after
all the
udev stuff but I can't quite remember. I tried lots of things
before
this one finally worked. Good luck, and if i manage to figure
out the
hotplug mounting I'll be sure to post it.
I did check .config to see if "CONFIG_HOTPLUG=y": it is.
Checking /proc/sys/kernel/hotplug is a good idea: it contains
"/sbin/udevsend", which is what I would expect to see.
And also, the udevd daemon is indeed running.
