OS=CentOS-5.2 media=Kingston 512Mb usb key

Problem: As 'root', when running a script resident on the external drive mounted at /media/disk I receive the following error:

/bin/sh: bad interpreter: Permission denied

The meduia is a 512Mb USB key formatted as ext2/3

# ll -rwx------ 1 root root 28 Jul 2 17:30 hello.sh

# cat hello.sh #!/bin/sh echo Hello World!

# which sh /bin/sh

I believe that this can be resolved by an entry in /etc/fstab but I cannot determine what entry to make.

# cat /etc/fstab /dev/VolGroup00/LogVol00 / ext3 defaults 1 1 LABEL=/boot /boot ext3 defaults 1 2 devpts /dev/pts devpts gid=5,mode=620 0 0 tmpfs /dev/shm tmpfs defaults 0 0 /dev/VolGroup00/LogVol03 /home ext3 defaults 1 2 proc /proc proc defaults 0 0 sysfs /sys sysfs defaults 0 0 /dev/VolGroup00/LogVol02 /tmp ext3 defaults 1 2 /dev/VolGroup00/LogVol04 /var/log ext3 defaults 1 2 /dev/VolGroup00/LogVol05 /var/www ext3 defaults 1 2 /dev/VolGroup00/LogVol01 swap swap defaults 0 0

From the logs I gather that the device is sda1

Jul 2 16:42:45 inet02 kernel: SCSI device sda: 1001472 512-byte hdwr sectors (513 MB) Jul 2 16:42:45 inet02 kernel: sda: Write Protect is off Jul 2 16:42:45 inet02 kernel: sda: assuming drive cache: write through Jul 2 16:42:45 inet02 kernel: sda: sda1 Jul 2 16:42:45 inet02 kernel: sd 0:0:0:0: Attached scsi removable disk sda Jul 2 16:42:45 inet02 kernel: EXT2-fs warning: mounting unchecked fs, running e2fsck is recommended Jul 2 16:42:46 inet02 hald: mounted /dev/sda1 on behalf of uid 500

I deduce from the various bits of information that I have gleaned thatthe proper entry in fstab should be something like:

/dev/sda1 /disk auto defaults,user,exec 0 0

However, this is an automounted, removable media. How do I do enable execute for this key and retain the auto mount capability? What impact will this have on other usb keys?
