Can't get script to run from symlink in etc/init.d

Hello folks

Got a problem with a script that loads a couple of kernel modules for scsi emulation for my cd/dvd (literally two lines). The script runs fine from its home in /usr/local/bin but when I create a symbolic link in /etc/init.d it refuses to recognise the file exists:

turknet01:/etc/init.d# ./cd-scsi-loader console
bash: ./cd-scsi-loader: No such file or directory

It refuses to recgnise the file under update-rc.d also. The original file has rwx permissions under root, r-- for all others. Anyone have any ideas? Sure this is a simple fix for some of you gurus out there;)

From a console window, do 'ls -l /etc/init.d/cd-scsi-loader'.

What's the output of ls?

If using LILO you want something like this in the append= line in the /etc/lilo.conf hdc=ide-scsi hdd=ide-scsi then run /sbin/lilo -v to update LILO and reboot. If using Grub you would either put them on the kernel line in the /boot/grug/menu.lst eg.

Code:

## ## End Default Options ##



title          Debian GNU/Linux, kernel 2.6.19-ck1-smp Default

root            (hd0,1)

kernel          /boot/vmlinuz root=/dev/sda2 ro hdc=ide-scsi hdd=ide-scsi

savedefault

This would be for the running kernel if you want all kernels to get this then edit this section.

Code:

## ## Start Default Options ##

## default kernel options

## default kernel options for automagic boot options

## If you want special options for specific kernels use kopt_x_y_z

## where x.y.z is kernel version. Minor versions can be omitted.

## e.g. kopt=root=/dev/hda1 ro

##      kopt_2_6_8=root=/dev/hdc1 ro

##      kopt_2_6_8_2_686=root=/dev/hdc2 ro

# kopt=root=/dev/sda2 ro hdc=ide-scsi hdd=ide-scsi

This would on every Grub update put the scsi emulation on the kernels available for booting. You should make sure to use the proper drive letters for the cd/dvd as if you make your hard drive use the emulation it will not boot so change the hdc and hdd as necessary.

To reply to both of you...

Output of ls -l ...:

Code:

lrwxrwxrwx 1 root root 28 2006-12-03 17:38 /etc/init.d/cd-scsi-loader -> usr/local/bin/cd-scsi-loader

Already had a look at this and couldn't see any probs - points to the right place and has the permissions.. any ideas bigrigdriver?

HappyTux, I already edited /boot/grub/menu.lst with the ide-scsi flags for my two drives. It seems to work OK except for one of the driver modules that isn't loaded on boot automatically:

Code:

/sbin/insmod sg

The ide-scsi module is loaded automatically and I want to avoid having to type this manually each time I log in.

Thanks in advance for any ideas

Just put the sg on a line by itself in the /etc/modules file and it will be loaded on boot.

That seems to have fixed it.

Thanks a lot for your help!
