I did not think that I would come back to you so quickly, but I am having an issue with RHEL6 implementation of kexec-tools (apparently adapted for kexec-tools 2.0) while testing crashdc on RHEL6 (the initial release).

Everytime I trigger a crash with 'kdump_post' set to /var/crash/scripts/kdump_post.sh I get the following from busybox : kdump-post.sh: applet not found

Copying data : [100%]
Saving core complete
kdump-post.sh: applet not found
dropping to initramfs shell
exiting this shell will reboot your system

For a while, I thought that my crashdc calling script was in cause, but I changed kdump_post.sh to one single "echo This is working" line and I still get the same thing :

# cat /var/crash/scripts/kdump-post.sh
echo "This is working"
/var/crash/scripts/kdump-post.sh
kdump-post.sh: applet not found
msh/ # /var/crash/scripts/kdump-post.sh
This is working

FYI, my crashdc scripts all work fine when I call them manually from the CLI.

I did not encounter this situation with SLES11, but from what I gather, it does not rely on busybox.

Maybe someone could suggest ways to further investigate this issue. I'm available to test.

Kind regard,

...Louis

I'm kind of suprised this is working at all. I don't see a #!/bin/sh or #!/bin/msh line at the top of the script. How does the system know what interpreter to use?
