goodday all, i have a question about creating menu items in the default file.
i would like to create a menu item that whipes the harddrive. i would like to boot into linux and start:
shred -vfz -n 7 /dev/hda
what is the best way to do this?
how to create a "small" bootable linux os, and let it automatically whipe the harddrive?
okee i guess i should have read some more!! :-)
This is how i would go about it?
# How can I put my own kernel for DRBL clients ? ^TOP^
Ex: The kernel you compiled yourself: name is 2.6.11-1.steven with CPU arch i686.
a. Put these files to DRBL server
1. 3 filres in /boot
System.map-2.6.11-1.steven
config-2.6.11-1.steven
vmlinuz-2.6.11-1.steven
2. put the kernel and modules in /lib/modules, like:
/lib/modules/2.6.11-1.steven
b. depmod -a 2.6.11-1.steven
c. /opt/drbl/sbin/mknic-nbi -k 2.6.11-1.steven -i i686
-k: specifly the kernel name
-i: specify the CPU arch for DRBL clients, such as i386/i586/i686
Actually I am not sure what's your question, so it's not easy for us to answer you.
If you mean you need some function to erase the harddisk, it depends on which way you want. You can do it manually in the command line prompt in clonezilla live CD, or you can write a dialog menu to run the command
shred -vfz -n 7 /dev/hda
OKee, this is what i would like to have.
I would like to create an menu item (in pxelinux.cfg/default) that would say:
Whipe: Whipe entire harddrive
When you choose that menu item, it should automatically start linux and the command:
shred -vfz -n 7 /dev/hda
how should i do that?
Looks like you mean you want to use grub/isolinux boot menu to do that. In that case, you have to hack a lot.
Some draft I suggest:
0. Put the kernel parameters in the append option in grub/isolinux config.
1. You have to write a service (let call it shred.sh).
2. The service shred.sh have to read the param/option from /proc/cmdline, then run command you want.
You may refer to /etc/rc1.d/S19ocs-run in the DRBL client to do that. I believe there must be another solution. If you find better one, please let us know.
Hi steven, what did you mean by "dialog menu"?

perhaps that is what i was looking for...
dialog is a problem to show the "dialog" menu, for example, when you run
/opt/drbl/sbin/ocs
it's based on dialog (or whiptail in Debian).
I think you can just refer to /opt/drbl/sbin/ocs to learn how to write a dialog menu to run the programs you want.
Good luck.
