Inotifywait restart script prevents reboot when started
Hi, maybe someone could help me optimizing this little script.


It works so far, but when running, reboot does not work. If kill inotifywait reboot from shell works. I think some optimization is required here.


This script starts at the end of the boot process, from an external device and starts a binary, logging the output, then inotify watches the config file, if changed it kills the binary and starts it again logging its output.


Code:
#!/bin/sh

wait 3

cmd="/usr/bin/binary -c /var/media/external/config.txt /var/media/external/config2.txt"

$cmd >> /var/media/external/binaries.log &

while inotifywait -e create,modify "/var/media/external/config2.txt"
do
    echo "A file or directory was modified."
killall -9 binary
wait 3
$cmd >> /var/media/external/binaries.log &

done

removable-media

removable-media(9P)                                        Kernel Properties for Drivers                                       removable-media(9P)

NAME

       removable-media - removable media device property

DESCRIPTION

       A  device  that  supports  removable  media--such  as CDROM, JAZZ, and ZIP drives--and that supports power management and expects automatic
       mounting of the device via the volume manager should export the boolean (zero length) property removable-media. This property  enables  the
       system to make the power state of the device dependent on the power state of the frame buffer and monitor. See the power.conf(4) discussion
       of the device-dependency-property entry for more information.

       Devices that behave like removable devices (such as PC ATA cards, where the controller and media both are removed at the same time)  should
       also export this property.

EXAMPLES

       Example 1: removable-media Entry

       An example of a removable-media entry from the .conf file of a driver is shown below.

       # This entry keeps removable media from being powered down unless
       # the console framebuffer and monitor are powered down
       #
       removable-media=1;

       Example 2: Implementation in attach()

       Below is an example of how the entry above would be implemented in the attach(9E) function of the driver.

       xxattach(dev_info_t *dip, ddi_attach_cmd_t cmd)
            {
            ...
                 if (ddi_prop_create(DDI_DEV_T_NONE, dip, DDI_PROP_CANSLEEP,
                     "removable-media", NULL, 0)) != DDI_PROP_SUCCESS)
                      goto failed;
            ...
            }
